Aria 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 6875 feet. Aria initially measures an angle of elevation of 16^{\circ} ∘

to the plane at point AA. At some later time, she measures an angle of elevation of 37^{\circ}

∘

to the plane at point BB. Find the distance the plane traveled from point AA to point BB. Round your answer to the nearest foot if necessary
