From the top of a 196-ft lighthouse, the angle of depression to a ship in the ocean is 10°. How far is the ship from the base of the lighthouse? Give your answer to the nearest foot. The boat is feet from the base of the light house. An airplane is headed for the airport, 18 miles away. If the airplane is at an altitude of 8000 feet, what is the angle of depression, to the nearest tenth of a degree, from the airplane to the airport? (1 mile = 5280 feet)
