In this lesson, we will learn how to solve real-world problems that involve angles of elevation and depression.

Students will be able to

recognize which angle is an angle of depression and which angle is an angle of elevation,
sketch a diagram from a real-world problem involving an angle of elevation or depression and use this to help solve the problem,
use right trigonometry along with the law of sines and cosines to solve problems involving one or more angles of elevation.
