Question

an airline pilot is flying at 10,000 feet in the air and sees his airport at angle of depression of 12 degrees. To the nearest foot how far is the pilot from the airport ? the pilot is ______ feet from the airport.

Answer 1

Using the sine function:

$\begin{gathered} \sin (\theta)=\frac{opposite}{hypotenuse} \\ \sin (12)=\frac{10000}{x} \\ solve= \\ x=\frac{10000}{\sin (12)} \\ x=48097ft \end{gathered}$
