From the deck of a boat, the angle of elevation of the top of an offshore oil rig is found to be 31°30'. The top of the oil rig is 127 meters above the level of the platform on which it stands. Assume that the head of the person doing the sighting is level with the base of the oil rig. What is the distance between the base of the oil rig and the boat?
