Determine the magnitude and direction of the position vector r which points from point A to point B.

A. r = 12 ft, = 70.5°, = 48.2°, = 131.8°
B. r = 12 ft, = 109.5°, = 131.8°, = 48.2°
C. r = 12 ft, = 70.5°, = 48.2°, = 48.2°
D. r = 12 ft, = 109.5°, = 131.8°, = 131.8°
Answer» B. r = 12 ft, = 109.5¬∞, = 131.8¬∞, = 48.2¬∞
