In going from one city to another, a car whose driver tends to get
lost and goes 30 km north, 40 km 45° northwest and 20 km south.
Find the magnitude (R = ?) and the direction (0= ?) at the
resultant displacement using analytical method (component method).

A = 50 km 90°
B = 40 km, 8 = 135°
C = 20 km, 0 = 270°
