1. An airplane’s velocity with respect to the air is mph and it is headed. The wind, at the altitude of the plane, is from the
SW (indicates it is blowing at a degree angle from the southwest) and has a velocity of mph. What are the resultant speed
(ground speed) and the direction of the airplane?

please show work and stuff
