Question

A woman stands on top of a building 400 feet above the ground. The angle of depression to
the top of a smaller building is 43°. If the buildings are 50 ft. apart, find how tall the smaller
building is.

Answer 1

You can use right triangles to find distances, if you know an angle of elevation or an angle of depression.The angle of elevation is the angle between the horizontal line of sight and the line of sight up to an object. For example, if you are standing on the ground looking up at the top of a mountain, you could measure the angle of elevation. The angle of depression is the angle between the horizontal line of sight and the line of sight down to an object. For example, if you were standing on top of a hill or a building, looking down at an object, you could measure the angle of depression. You can measure these angles using a clinometer or a theodolite. People tend to use clinometers or theodolites to measure the height of trees and other tall objects. Here we will solve several problems involving these angles and distances. The solution depends on your height, as you measure the angle of elevation from your line of sight.

Answer 2
