Question

The angle of elevation from object A to object B is always ______ the angle of depression from object B to object A.choice:less thanunrelated togreater thanequal to

Answer 1

Given Object A and Object B, you need to remember that, by definition:

- An Angle of Elevation is the one formed by the line of sight of the observer (a horizontal line) and an object above the line of the sight.

- An Angle of Depression is the one formed by the line of sight of the observer and an object that is below that line.

Then, you can make the following drawing of objects A and B:

Notice that the red line represents the line of sight of Object B and the blue line is the line of sight of Object A.

You can identify that the the angles "a" and "b" are Alternate Interior Angles. Therefore, they are congruent.

Hence, the answer is: Last option.
