1 4 DC-9 aircraft leaves an airport from a runway whose bearing is N46E. After flying for mile, the pilot requests permission to turn 90 and head toward the southeast. The permission is granted. After me airplane goes 1 mile in this direction, what bearing should the control tower use to locate the aircraft? What is the bearing that the control tower should use to locate the aircraft? (Do not round until the final answer. Then round to the nearest tenth as needed.)
