Peyton spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 6725 feet.
Peyton initially measures an angle of elevation of 15° to the plane at point A. At some
later time, she measures an angle of elevation of 33° to the plane at point B. Find the
distance the plane traveled from point A to point B. Round your answer to the
nearest foot if necessary.
