The angle of elevation is the angle between a horizontal line and the line joining the observer’s eye to some object above the horizontal line.
The angle of depression is the angle between a horizontal line and the line joining the observer’s eye to some object beneath the horizontal line.
In real world situations, we often discuss the angles of elevation and depression. The angles of elevation and depression is used often in word problems, especially those involving a person’s line of sight as they look up at an object.
This video will explain what is the angle of elevation and what is the angle of depression.
It will also give some examples of how to use the angles of elevation and angles of depression.
Angle of Elevation/Depression Story Problems
Examples:
The angle of elevation from point A to the top of a cliff is 38 degrees. If point A is 80
feet from the base of the cliff, how high is the cliff? Let x be the height of the cliff.
