A ski run is 1200 yards long with a vertical drop of 308 yards. Find the angle of depression from the top of the ski run to the bottom.

The vertical drop created an angle of 90 degrees.

Therefore, you have a right triangle.

Let's name the ski run AB, and the vertical drop BC.

Angle B would be 90 degrees.

We have two measurements AB = 1200 and BC = 308 so we can find the third measurement AC by doing pythagoras:

1200^2 + 308^2 = 1239 yards

now with the sine law

1239/sin90 = 308/sin(angle of depression)

angle of depression = sin-1(308 x sin90/ 1239) = 14.4 degrees

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
