A boat is heading towards a lighthouse, where Yaritza is watching from a vertical distance of 139 feet above the water. Yaritza measures an angle of depression to the boat at point A to be 21°. At some later time, Yaritza takes another measurement and finds the angle of depression to the boat (now at point B) to be 50°. Find the distance from point A to point B. Round your answer to the nearest foot if necessary.
