Answer:

  27.6°

Step-by-step explanation:

It can help to draw a diagram.

The angle of interest is the angle in a right triangle that has 23 ft as its adjacent side and 12 ft as its opposite side. The tangent relation is helpful:

  Tan = Opposite/Adjacent

  tan(d) = 12/23

The inverse tangent function is used to find the angle when you know the tangent:

  d = arctan(12/23) ≈ 27.55°

The angle of depression is about 27.6°.
