Question

An observer (O) spots a plane flying at a 42 degree angle to his horizontal line of sight. If the plane is flying at an altitude of 15,000 ft., what is the distance (x) from the plane (P) to the observer (O)?

A right triangle is shown with one angle marked 42 degrees, one side marked x and the height marked 15000 feet.

10,035 feet

16,648 feet

20,188 feet

22,417 feet
