An angle of depression

The lighthouse sees a ship at an angle of depression of 25°. The observer from the lighthouse is 82 m above sea level. How far is the ship from the top of the lighthouse?

Correct answer:

x =  194 m

Step-by-step explanation:

h=82 m α=25   sin α = xh  x=h/sinα=h/sin25° =82/sin25° =82/0.422618=194=194 m
