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

I4 Angles of Elevation and Depression. Let C represent the ice climber and let B represent the bottom of the opposite side of the crevasse. I4 Angles of Elevation and Depression. The angle of depression is the angle between a horizontal line from the observer and the line of sight to an object that is below the horizontal line. What is the horizontal distance from the plane to the tower? To make this website work, we log user data and share it with processors. Identify the pairs of alternate interior angles.

Finding Distance by Using Angle of Depression An ice climber stands at the edge of a crevasse that is ft wide. Let A represent the tip of the shadow, and let B represent the top of the Space Needle. Let C represent the ice climber and let B represent the bottom of the opposite side of the crevasse.
