Find the angle between the vectors to the nearest whole number. Use a calculator. u = cos 80 i + sin 80 j, v = cos 25 i + sin 25 j 35.6' 180' ~55' O ~ 1.5' O ~ 45.4 18. Choose the best answer. Find the unit vector u in the direction of v. Vector v has an initial point (0, 9) and a terminal point (-3, 2) O 2 U = V58 V58 O 3 U = V58 V58 O u = 3 158 158 00:50:35
