Question

In the following figures, identify the segment that represents the line of sight, and identify the angles (if any) that represents the angle of elevation or angle of depression.

Answer 1

Given :

Figure attached

To find:

To identify the segments representing angle of elevation, angle of depression and the line of sight.

Solution:

In the figure attached,

Figure        Angle of elevation    Angle of depression   Line of sight

1).                                                             ∠BAC                         AC

2).                          ∠BAC                                                           AB

3).                          ∠BAC                                                           AB

4).                                                             ∠BAC                        AC

5).                                                             ∠BAC                        AC

Line of sight:

A straight line joining the object and the observers eye.

Angle of elevation:

Angle (above the horizontal) between the line of sight and the horizontal.

Angle of depression:

Angle (below the horizontal) between the line of sight and the horizontal.
