A person measures the angle of depression from the top of a wall to a point on the ground. The point is located on level ground 62 feet from the base of the wall and the angle of depression is 52°. How high is the wall, to the nearest tenth of a foot?
We can use the tangent here
tan (52) = H / 62 where H is the wall height......rearrange as
H = 62 * tan(52) ≈ 79.4 ft.
Here's a pic ......angle DCB is the depression angle
