Question: Determine the magnitude and direction of the resultant FR = F1 + F2 + F3 of the three forces by first finding the resultant F'

Determine the magnitude and direction of the resultant FR = F1 + F2 + F3 of the three forces by first finding the resultant F' = F1 + F2 and then forming FR = F' + F3.

Given:
F1 = 30 N
F2 = 20 N
F3 = 50 N
θ = 20 deg
c = 3
