A pinball bounced around its machine before resting between two bumpers. Before the ball came to rest, its displacement (all angles measured up from x axis) was recorded by a series of vectors. 83 cm at 90° 55 cm at 159° 65 cm at 221° 41 cm at 285° 61 cm at 21°. determine the total displacement\'s magnitude and direction:
