Answer:
9/41
Step-by-step explanation:
The base line is
The square root of (41*2-40*2),=9
Thus, cosC=9/41
In a right triangle, the hypotenuse is always the longest side. Plus, the hypotenuse squared has to equal the sum of the squares of the other 2 sides. For the first "triangle" above: does
![14 ^{2} =5 ^{2} +4 ^{2}](https://tex.z-dn.net/?f=14%20%5E%7B2%7D%20%3D5%20%5E%7B2%7D%20%2B4%20%5E%7B2%7D%20)
? Let's check. 196 = 25 + 16 so does 196 = 41? Obviously not. So that is not a right triangle. Let's check the second one the same way. Does
![5 ^{2} =3 ^{2} +4 ^{2}](https://tex.z-dn.net/?f=5%20%5E%7B2%7D%20%3D3%20%5E%7B2%7D%20%2B4%20%5E%7B2%7D%20)
? 25 = 9 + 16. Does 25 = 25? Of course it does! So 1 is not a right triangle, but 2 is!

Answer:
264ft^2
Step-by-step explanation:
First find the area of the body of the house which is the rectangle.
18*12=216
Then find the are of the triangle or roof given by 1/2(b)(h)
1/2(12)(10)=60
Then Find the area of the window which is 3*4=12 and subtract 12 from 60 to find the area of the roof with the window.=48
Add 48 the roof and 216 the rectangle to get total painted area. =264 ft^2
