Question 3 of 10
3. Question
The ___________ is the angle between the horizontal and the line of sight to an object when the object is below the horizontal level.
Correct
The angle of depression is the angle between the horizontal and line of sight to an object when the object is below the horizontal level.
The angle of depression is formed when the observer is higher than the object he is looking at. It is the angle between the horizontal line and the line joining observer’s eye and the object. It plays very important role in determining the heights and distances.
