Dan 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 6350 feet. Mei Mei initially measures an angle of elevation of 17 degrees to the plane at point A. At some later time, she measures an angle of elevation of 36 degrees 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.

A boat is heading towards a lighthouse, where Dominic is watching from a vertical distance of 114 feet above the water(in the lighthouse). Dominic measures an angle of depression to the boat at point A to be 6 degrees. At some later time, Dominic takes another measurement and finds the angle of depression to the boat (now at point B) to be 32 degrees . Find the distance from point A to point B. Round your answer to the nearest foot if necessary.
