A boat is heading towards a lighthouse, where Natalie is watching from a vertical distance of 140 feet above the water. Natalie measures an angle of depression to the boat at point AA to be 12∘∘. At some later time, Natalie takes another measurement and finds the angle of depression to the boat (now at point BB) to be 27∘∘. Find the distance from point AAto point BB. Round your answer to the nearest foot if necessary
