Question

On a test flight, during landing of the space shuttle, the ship was 325ft above the end of the landing strip. It then came in on a constant angle of 7.5 degrees with the end of the landing strip. How far from the end of the landing strip did it first touch ground?

Answer 1

This is what I get:

First draw a picture (a triangle) and label the sides. The height is 325 ft.
The hypotenuse we don't care about. We want to find the horizontal leg of the triangle which I called x.

tan 7.5= 325/x then:

x = tan7.5/325

x = 2468.62 ft

Answer 2

325 * (tan 7.5) = distance from end of landing strip at touch down.
