A boat is heading towards a lighthouse, whose beacon-light is 141 feet above the water. From point AA, the boat’s crew measures the angle of elevation to the beacon, 7^{\circ} ∘ , before they draw closer. They measure the angle of elevation a second time from point BB at some later time to be 14^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
