The pilot of an airplane flying at an elevation of 5000 feet sights two towers that are 300 feet apart. If the angle of depression to the tower closer to him is 30 degree, determine the angle of depression to the second tower

Solution:

The angle of depression to the second tower is x

tanx = 5000/(5000*sqrt(3)+300)

x=29.2

So the angle of depression to the second tower is 29.2 degree
