#### PROBLEM SOLVING LESSON 8-4 ANGLES OF ELEVATION AND DEPRESSION

What is the horizontal distance between the plane and the airport? An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line. Estimate the height of the tree. Share buttons are a little bit lower. Objectives Use trigonometry to solve problems involving angle of elevation and angle of depression. Round to the nearest meter. It is an angle of elevation.

Angles of elevation and depression are equal. Let y be the depth of the crevasse. Angle of elevation and depression. Let y be the depth of the crevasse. Part I Classify each angle as an angle of elevation or angle of depression. What is the horizontal distance between the plane and the airport?
