Worksheet: Angle of Depression

In this worksheet, we will practice identifying the angle of depression and determining it in right triangles.


A person in an office building looks out of a window from a height of 6 m. They see a cat on the sidewalk 10 m from the building. From the person, what is the angle of depression of the cat? Assume the sidewalk is horizontal.

In the given diagram, Fady observes a buoy in the sea below him from a point 6 ft above a 45 ft cliff. He has been told that the perpendicular distance from the buoy to the base of the cliff is 60 ft. What is the angle of depression, in degrees, from Fady to the buoy? Give your solutions to two decimal places.
