A plane leaves Seattle, flies 75.0{\rm mi} at 22.0^\circ north of east, and then changes direction to 55.0^\circ south of east. After flying at 124{\rm mi} in this new direction, the pilot must make an emergency landing on a field. The Seattle airport facility dispatches a rescue crew. In what direction should the crew fly to go directly to the field? Use In what direction should the crew fly to go directly to the field? Use components to solve this problem. how far should the crew fly to go directly to the field? Use components to solve this problem. How far should the crew fly to go directly to the field?
