Final answer:
To determine the direction of the resultant displacement, use the head-to-tail method and measure the angle between the east-west line and the line connecting the starting point to the final position.
Step-by-step explanation:
The direction of the resultant displacement can be determined by using the head-to-tail method. First, represent each displacement vector graphically with an arrow, labeling them A, B, and C. Then, add the vectors by connecting the tail of one vector to the head of the previous vector.
Finally, determine the direction of the resultant displacement by measuring the angle between the east-west line and the line connecting the starting point to the final position.
