Angle of Elevation and Depression

1. The angle of elevation of an object as seen by an observer is the angle between the horizontal and the line form the object to the observer's eye (the line of sight).If the object is below the level of the observer, then the angle between the horizontal and the observer's line of sight is called the angle of depression

6. Ex:
7. Let x m be the distance of the object from the base of the cliff.

   

   

   

   So, the object is 59.30 m from the base of the cliff.
