Question

An aerial photographer who photographs real estate properties has determined

that the best photo is taken at a height of approximately 405 ft and a distance
of 868 ft from the building. What is the angle of depression from the plane to
the building?
The angle of depression from the plane to the building is
(Round to the nearest degree as needed.)
angle of
depression
868 ft
angle of
elevation
405 ft

Answer 1

We can use trigonometry to find the angle of depression from the plane to the building:

tan(angle of depression) = opposite / adjacent
tan(angle of depression) = 405 / 868
angle of depression = arctan(405/868)
angle of depression ≈ 25.2 degrees

Therefore, the angle of depression from the plane to the building is approximately 25.2 degrees.
