A passenger is traveling on an airplane. The velocity of the plane with respect to the air is 170 m/s due east. The velocity of the air with respect to the ground is 46.0 m/s at an angle of 30 west of due north. What is the heading of the plane with respect to the ground as measured clockwise from due north? (e.g., 0 represents due north and 90 represents due east.) = east of due north
