boat heading out to sea starts out at Point A, at a horizontal distance of 1390 feet from a lighthouse/the shore. From that point, the boat's crew measures the angle of elevation to the lighthouse's beacon-light from that point to be 7°. At some later time, the crew measures the angle of elevation from point B to be 4°. Find the distance from point A to point B. Round your answer to the nearest foot if necessary.
