From the top of a 300-ft lighthouse, the angle of depression to a ship in the ocean is 25°. How far is the ship from the base of the lighthouse?

Respuesta :

Refer to the diagram shown below.

Let d =  distance of the ship from the base of the lighthouse.

By definition,
tan(25°) = 300/d
d = 300/tan(25°) = 643.35 ft

Answer:  The distance is 643.4 ft (nearest tenth)
