Measure the length of the resultant vector – it should be \(10cm\) long. This corresponds to \(50m\) according to your scale. (Line AC in the diagram below). Measure the angle BAC (θ below).

Two forces can be added together to find a resultant force ... of the parallelogram shows that the resultant force is 5 newtons (N) acting at an angle of 37° to the horizontal.
