Join Nagwa Classes

Attend live Mathematics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

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

Students will be able to

recognize which angle represents an angle of depression and which angle represents 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, namely, the tangent ratio, to solve problems involving one or more angles of elevation.
