A ship is 750 meters from a light house which is 50 meters tall. What is the angle of depression from the top of the lighthouse to the ship?

2 answers

same as the angle from the horizon to the top of the lighthouse from the ship
tan T = 50/750
T = 3.81 degrees
make your sketch

angle at water --- Ø

tanØ = 50/750 = 1/15
Ø = appr 3.81°

which is also the angle of depression
