## Trigonometry (10th Edition)

The angle of depression is $37.6^{\circ}$
We can use the height $h$ and the horizontal distance $d$ to find the angle of depression: $tan~\theta = \frac{h}{d}$ $\theta = tan^{-1}(\frac{h}{d})$ $\theta = tan^{-1}(\frac{39.82~ft}{51.74~ft})$ $\theta = 37.6^{\circ}$ The angle of depression is $37.6^{\circ}$
