Question

Two ladders are leaning against a wall at the same angle, as shown. How long is the shorter ladder? picture attached

A. 28 ft

B. 175 ft

C. 25 ft

D. 20 ft

Answer 1

Picture?

Answer 2

The two triangles are similar since they both are leaning at the same angle and are creating right triangles.

so we can say

(length of longer ladder)/(height of longer ladder) = (length of shorter ladder)/(height of shorter ladder)

70/50 = x/20

Solve for x...

Answer 3

Answer 4

I'm not good at math.

Answer 5
