Question

WILL GIVE MEDAL!! A flight of stairs is supported by two columns as shown. What is the distance from the base of the stairs to the tallest column?

Answer 1

I saw the image. It formed 2 right triangles. 1 small and 1 big.
small triangle has a long leg of 4 feet and hypotenuse of 6 feet.
big triangle has a long leg of (x) and hypotenuse of 6 + 12 ft.

proportion:

4/6 = x / 18
4 * 18 = 6x
72 = 6x
72/6  = x
12 = x

The distance from the base of the stairs to the tallest column is 12 feet.
