Okay, 11 3 area of parallelogram situation triangles payment. So we should talk the formulas before maybe in Middle School. Sitting up here for the area of the shape, but now we're going to have Trigg added in. So that means we're going to specialize triangles. We're going to have sine cosine tangent to find some missing information. What is a parallelogram? What is the formula for the area? parallel Well, apparently Grandma's my question. Slide a rectangle right pushed on it. Alright, I want to say Little Triangle right here and drive over here. Right fit at this one is gone. It's been moved in but I can. Hey, I've got a wreck which means it's really the same formula as the area rectangle letter from no further action. Hi. Hi Vic, Taylor. Hi. Slanted line here is not as a parallelogram. If so, right killer Heights right here there so we want and The formulas it's Joe area contacts. Andy hi, it's Aviva this killer hi. So you said that we've got some Rollo right triangle here when we go on a hike or we may need to use it on it. Okay, again, it's umbrella. this black parallelogram Well remember that our formula. Is base 10 types for this parallelogram? Brett 11 Now what type Ben Stiller height not the slanted line, but Jake. Does that times 4 which means our area is 11 centimeters time for leaders usually gets 44 with 7 centimeter where I do. Remember that was saying how many square centimeters inside of rice and 44 square that would fit inside finding the area? Okay. area of a parallelogram red parallelogram again, it's Bill FaceTime type this time. face Be careful cuz this is windy up here with Jesus plenty down here. But this is not a part of the parallelogram by the car longer. We don't want to include that 5 there. Will you just let me use 20? Valley careful hi is the perfect it up now? I can be drawn on the inside the parallelogram or even Monday else. I could just drive over here and it would be on the inside. Which means alright. Not a plan for lions. Anytime. Thanks. 120 centimeters Okay, the Holograms are pretty straightforward for. Hi, Dr. We have just English with Farmers is the ones that I think II Amit face to listen thinking some Cricket on the church. Looks that was a black girl. I was Ram up here. Now we have the right. Are Bates is how much? 24 rice We don't have the Heights. But we do have at 63 angle. Let me in to the right 3069. So if opposite from 30th 4. For radical sorry took me back. Hi, it's Laura radical 3. So our area now. 84524 remember we both supplied the outside numbers together. everybody in numbers together She gets 96 radical 3 centimeters work. Can you can leave it in simplest radical form? When you have the right line, alright, there you go into decimal. Warm if you that it was to be about 1. He 6.373 Square. Again, I want to see if Incredibles Pharmacy have a special right time. Okay. How about this read a parallelogram? Hi Mario, this one. Now for this one, we don't have a special right triangle, right? We have 20 degrees. And we're tight. Gene is going to go all the way across but we're Can we have some time today? We need to find. Well the height. Hello, this is right triangle, and we wanted to go. So we can use mine Coast 10 degrees we have this and we have that apartment which one? The ratio for the sign of 20 degrees is equal to 8/6. Name is Lee cross X is going to eat go 6 times the sign of 20 degrees. We're going to have to put into our later. That would I guess coming here. 2.1 We're going to punch in 2.1 here now for our hike which means we can find the area 16 and 2.1. relation 31.5 again c squared questions on how the big ones what about the Papasan find the area of ice? We took a parallelogram and way into work, right and that's how we got. trapezoid I haven't been there. Hi, we have a big job and he's on the top. Kathleen this into a different shapes What what is the one I looked it over and put it right next to the other one. like that Now, what's up? We have a parallelogram. Hey. Have a parallelogram now if we flipped it over to me. This one down here is actually one up so nice and this one here. So we can use our parallelogram Hula Hut. So please do that is going to be nice one. right to be 1 plus the 2 if this is C sub wonderful Jesus Hi Chris, really face, too and they Salon cheaper for the base. OurTime by our hike well, that would give us the area of this giant Carlisle agree, but we don't want area design parallelogram. But right now we only want to stop on by thing. We do get the area just passed away. Okay. Bye. So here's The area of a trapezoid Which we got using our parallelogram to help us. Here's our formulas the area 5/2 days one, two three. Who your friend person for your order of operations here parentheses exponents location? Division addition right? That means we have to add first before. black here You want the area? Okay. Well this one we're going to do our formula 1/2 Sage one blessed day, too. Bye. Bye. Let's f****** plan. Well, that's 1. 20 is fine, but we can just use one of them 20 with Facebook. Sounds about right. So remember you are hi. I'm waiting to First so we're going to do 20 + 424. Now we take half of 24 we can take the Stone Age cash only one half of 24. hello, this is 72 centimeters where Okay. What about this a bread trapezoid down here? Okay, Taco Boy the book. Tonight right because we know that the both sides here. I can do a shadow. So keep that in mind also keep in mind that you can draw in. I don't have it brought in and see if that will help you. Okay. Got it. Now I've got this little. Trevor ago so I can see it but 22 at the bottom. Okay. 22 at the bottom of my policy, but I need to draw in my car on my house, but the nice password, so that means that these triangles on each side are congruent to each other. so This one right here. This part is also. just 22 goes all the way up cost then 22 - 10 is What is the same thing on both of these nice day? So it's 22 my 10123 ÷ 2 to be fine. We don't have it. So we don't know if it's the right phone gold or if we can use plant and we have a ride Bible and we need to find Vespers. Hi. What are we doing? I have your answer on this right we can use the battery. apartment 1000 some of you make sure TCC mistake. We're going to be close to 10 square. So that's 36 and 100 If I subtract I'll get 60. Hi this age. Now we can't find the area of the trapezoid. So 1/2 again that 1 plus a 2 times if I the hype. Time our base 1 is 22 our base 2 is 10. Alright, we found but 8. Okay, so let's make we are so we're going to take one. 32 + 2 by 8 now this time I think it'll be easier to take 1/2 of 8, so I'm going to do that, but I'm not going to take one half of 32 only 1/2 of one of them. So that's 32 x 4 and If I multiply 32104 I guess. 28 this is not my place. Weeks we'll find the area and we're formation information. Mariah this one What is 1/2 - 1 + 82 divided now? We have the one we're missing base to work a lot of information here. We have a right triangle where it says produce. Nike triangle and 90 is 10. So what's up, buddy? T.I. Radical 3 now if this bar down here, it's 5 just part of Pierre it's also now. It's got 1/2 big one is 25 now they do is 30 right be and prior thing is III. Allie hi with this by radical 3 So, let's see man that I'd firstly at Birth and I guess she V. Hi Brad, it's Alfredo this time. They're both odd number. So I don't think it's going to really help me that much to 1/2. 5 1/2 or 5 because I'm going to end up getting a decimal. So I'm going to Lowe's 5510 / and get home. To you by radical 3 and then I'm going to take 1 months of two 575. How do I get? 137.5 radical 3 I gave her a try and we can leave it in simplest radicals. Okay, well before but what's the area? We're trying to know if it ever time. Alright, if we were to cut a rectangle, it was a triangle. So it's a 1/2 times. All right now there. Look at this down here. Remember just like with a parallelogram just like what the prices so I have to be the perfect time if we can have it on the inside. Just trying to learn some kind of sleeping habit. So in this case, area is 1/2 our base with careful the blue triangle area that we're finding so our face is 8 or 5 is like fun. So we're going to take 1/2 to 8 with Who are 4 x 20 meters? Hi, it was given to us, but we don't have to have to find that time. So again, we've been having some curtain on a trade but that missing Hi, Dan, I possibly perpendicular to the bank. So keep that in mind. Okay, they're going to find the area of a b**** trying. Mad at 20 goes all the way across. That we can draw in our hike so let's draw in our Heights. Where it is running a high. Hi, we don't know. It made look like it. We don't know because not we don't have it 10/3 or whatever. the only time they cut Is an isosceles triangle and we don't know if they'll fit radical crew we can do this is 10 and 10, but we do have a right triangle over here. In fact, we have a 45 4590 triangle. It's me. Hoppin be here is a tropical School 45 Jim. Really? But we really didn't eat cuz we have the entire base here so we can find the area one switch 20 by the high which is the sound is 8 but I take 1/2 of plenty. Hey Ty. It's 8 I'm sorry 8:18 meter Square. So you can find the area this time. Hi get in this house. So let's draw in our house here. I never drawn the height is going to we don't know what couldn't have only worth $5, but we have a 2 degrees it's not a pressure right angle. I have to use sine cosine tangent do it now. I want to find the house right now. So it's all the way as well. I don't know what discard little find the list so I can't use the club to help me cuz it's not civil rights point I can use is the . So I have from this issue. I have the opposite and I have the hypotenuse. So which racy am I using? That's 9 ratio that sign of 62 degrees is equal to the office at 8. When I crossed X x cosine of 62, so now we have to come back into our calculator if we do that for you. Ramen your text Test 7.1. Good. Okay. Now I find the area the area is going to live there to come and go 1 x 5. Lacrosse is 12 blue triangle. Our high is 7.1 take 1/2 of 12 this 50 x 7.1. 7 it's 42.616 Point 642 point. I swear for our area. Okay. How about this time now just saw your bye. Download careful that number you can use the 1 number if you can't use the help you find your missing information. can draw in our Heights now this Hi, Miss upside down here with me in the Myspace would be gone in like. Now if I want to find out hi again, it's Beth right triangle. I need to use the size. But remember the 22. Goes all the way across so I can't use 22 to help me. I need to use because he's part of the small white sign which means office and hypotenuse, which is just buying ratio. So just Hi 36 with a call the office 8/8. When I crossed multiply I'm going to get 18 x the 36 if we funds back into my calculator. What do we get? 10.6 Okay. Now we can't find the area. There's a 1/2 day fun time. What's the baits 22 what type? Found it. It's 1.6. We're going to have 1/2 to 22. It is 11 and then we're going to do a Levin X 10.6. Our area here is going to equal 116.6 centimeter squared. using flying cosine tangent our trigonometry we will Able to calculator is an and exam. So one of the car scientific calculators with us every day Greg Nixon all the way.
