8-4 Angles of Elevation and Depression - GEOMETRY

The video tutorial covers angles of elevation and depression, explaining their meanings and differences. It uses an example problem involving an air traffic controller to demonstrate how to calculate the horizontal distance between a plane and an airport using the tangent function and the concept of SohCahToa. The tutorial emphasizes the importance of understanding these angles in real-life scenarios and provides a step-by-step solution to the problem, ensuring the viewer understands the process of solving such geometric problems.
