Find the sum of u + v. given that | u = 42, v| = 31, and 0 =90, where 0 is the angle between u and v. Give the magnitude to the nearest tenth and give the direction by specifying to the nearest degree the angle that the resultant makes with u The magnitude of u + v is (Round to the nearest tenth.) The angle that u + v hakes with u is degrees (Round to the nearest degree.)
