Trigonometry Method of Vector Addition

11. Three forces act on an object to produce equilibrium, which means that the vector sum of the forces = 0. If one force is 33 N, north and the second force is 44 N at 60( N of E, find the 3rd force needed to produce equilibrium. (note – this 3rd force is known as the equilibrant) (74 N, 73( S of W) 12. ................
