Question

Which is the angle of the depression from A to B?

Answer 1

The angle of depression at A is ∠1

Option 3 is correct

Explanation:

Angle of depression: It makes angle at top point with horizontal.

We need to find angle of depression from A to B. We will find the angle at point A with horizontal.

At vertex A make only one angle with horizontal.

∠1

For depression: We see from top to bottom and angle of depression makes at top.

Angle of depression at A = ∠1

Hence, The angle of depression at A is ∠1

Answer 2

An angle of depression involves you at a point and looking downward, with your eyes as the vertex. (An angle of elevation goes up from your line of sight.)

In the picture, imagine your eyes are point A. To make an angle of depression, you look downward. The angle made is angle #1, as none of the other angles use A as a vertex.
