Hi, I need help

With reference to Figure 1.1, determine the magnitude of the resultant force F, = Fl +I=2 using the taw of cosines. Resoive the force F2 into components acting aiong the u and v axes and determine the magnitude of the components. Assume CI = 22, [3 = 25, 1! = 20, 6 = 18, F; = 4 kN, F2 = 5 kN. Figure
