Step 1: 2-6

The parallelogram is drawn by a line from F1’s head which is parallel to F2, and another line from F2‘s head which is parallel to F1. The point of intersection of the line is met by the resultant force FR. Draw the parallelogram and the vector triangle.

Step 2

Understand which the sum of the consecutive angles is equal to 180°.

Step 3

Apply the law of sines in the vector triangle.
