Makayla 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 5750 feet. Makayla initially
measures an angle of elevation of 16° to the
plane at point A. At some later time, she
measures an angle of elevation of 31° 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.
