Aradio tower is located 400 feet from a building. from a window in the building, a person determines that the angle of elevation to the top of the tower is 41 ∘ 41∘ and that the angle of depression to the bottom of the tower is 33 ∘ 33∘. how tall is the tower?

The solution is:

The height is computed by:

h(t) = h(1) + h(2) 

h(1): 

tan41 = h(1) / 400ft 

h(1) = 400(0.8693) = 347.72 ft 

h(2): 

tan33 = h(2)/400 ft 

h(2) = 400 (0.6494) = 259.76 ft 

So combining the two:

h(t) = 347.72 + 259.76 = 607.48 feet 

The tower is 607.48 feet tall.
