Question

2. Define the following

a. Angle of elevation
b. Angle of depression ​

Answer 1

Answer:

The upward angle from the horizontal to a line of sight from the observer to some point of interest is known as angle elevation

the downward angle from horizontal to a line of sight from the observer to some point of interest is known as angle depression

Answer 2

he angle of elevation of an object as seen by an observer is the angle between the horizontal and the line from 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.
