This resource has been contributed by Winpossible, and can also be accessed on their website by clicking here - Angles of Elevation and Depression
This mini-lesson introduces and walks you through the basic concepts of the trigonometric functions and explains how you can solve word problems that involve angle of elevation and depression. It should help you to enhance skills to enable applying with the distance formula knowledge, in everyday practical situations and real life applications. You will learn it with the help of some examples, practice questions with solution, using video and explanation in own handwriting by the instructor that brings in an element of real-class room experience.
The angle of elevation is the angle formed by a horizontal line and the line joining an observer's eye or an object to some other object above the horizontal line. On the other hand an angle of depression is the angle formed by a horizontal line and the line joining an observer's eye or an object to some other object beneath the horizontal line. It also covers the steps or method to find angle of elevation or angle of depression when the distance is known, alternatively the method to find out the distance or length, given the angle of elevation or depression. For example, if a tree is 10 feet in height and casts a shadow of length 15 feet, then the angle of elevation from the end of the shadow to the top of the tree is 34°.
