Q2. An airplane starting from airport A flies 470km east, then 317km at 57.3 degrees west of north, and then 492km north to arrive finally at airport B. The next day, another plane flies directly from A to B in the straight line. In what direction should the pilot travel in this direct flight? Use counter clockwise as positive angular direction from due east between the limits of -180 degrees and 180 degrees. Suppose there is no wind during these flights. Respond in units of degrees.
