high wishes to estimate the width of the pile. He visually locates two rocks the ground below, at the base of the sand pile. The rocks are on opposite sides of the sand pile, and he and the two rocks are in line with one another. If the angles of depression from the top of the sand pile to each of the rocks are 27° and 19°, how far apart are the rocks? Angle of Depression From a plane 3,000 feet in the air, the angle of depression to the beginning of the runway is 3° 50'. What is the horizontal distance between the plane and runway? (That is, if the plane flew at the same altitude, how far would it be to the runway?) Give your answer to the nearest tenth of a mile. (5,280 feet = 1 mile) Angle of Depression From the edge of a platform 25.1 meters high, a diver notices the angles of depression to each end of the pool are 14.7° and 78.9°. What is the length of the pool?
