Answer:
125
Step-by-step explanation:
Do lulus way. If you change the angles, you will not have a pentagon anymore. If you subtract, it wouldn’t be the same ratio:)
You are correct!
Step 1:Write what you know
Madeline's Height: 6 ftMadeline's Shadow: 108 in
Friend's Height: X (we use X as a variable because his height is unknown)Friend's Shadow: 108 in - 1.5 ft 108 in - 18 in 90 in
Step 2:Set up proportions
6 x----- = -----108 90
Step 3:Cross Multiply & Solve
108x = 540x = 5 ft tall
It is given that the triangle is isosceles right triangle . And in an isosceles right triangle the legs are equal . Let each leg be of x units. Now we use pythagorean identity, which is
![a^2 +b ^2=c^2](https://tex.z-dn.net/?f=%20a%5E2%20%2Bb%20%5E2%3Dc%5E2%20)
![x^2 +x^2 = 8^2](https://tex.z-dn.net/?f=%20x%5E2%20%2Bx%5E2%20%3D%208%5E2%20)
![2x^2 = 64](https://tex.z-dn.net/?f=%202x%5E2%20%3D%2064%20)
![x^2 = 32](https://tex.z-dn.net/?f=%20x%5E2%20%3D%2032%20)
![x = 4 \sqrt 2](https://tex.z-dn.net/?f=%20x%20%3D%204%20%5Csqrt%202%20)
So the length of each leg is ![4 \sqrt 2 .](https://tex.z-dn.net/?f=%204%20%5Csqrt%202%20.%20)
