A diver sees a school of fish. The angleof depression from the diver to the fish is 62 degrees. If the fish are 12 ftdeeper than the diver, how far would the diver have to swim to get to thefish?

Answer :

Using cosine function:

[tex]\begin{gathered} \cos (\theta)=\frac{adjacent}{hypotenuse} \\ so\colon \\ \cos (62)=\frac{12}{distance} \\ solve_{\text{ }}for_{\text{ }}distance \\ distance=\frac{12}{\cos (62)} \\ distance=25.56ft \end{gathered}[/tex]
