Answer :
you have a right triangle and the length of the hypotenuse and one of the legs.To find the measure of the angle of depression use the next trigonometric function:
[tex]\begin{gathered} \cos \theta=\frac{a}{h} \\ \\ \cos \theta=\frac{85ft}{92ft} \\ \\ \theta=\cos ^{-1}(\frac{85}{92}) \\ \\ \theta\approx22.5 \end{gathered}[/tex]Then, the closest value to the angle of depression (22.5) is 22º
