I want to know if the set up is correct. This is all I need.
An observer standing on top of a vertical spots a house in the adjacent valley at an angle of depression of 12°. The cliff is 60m tall. How far is the house from the base of the cliff?
Set up:
Let d = distance between the house and base of the cliff.
tan(12°) = 60/d
