A large wrecking ball is held in place by two light steel cables - 5.6

5.6 •• A large wrecking ball is held in place by two light steel cables (Fig. E5.6). If the mass m of the wrecking ball is 3620 kg, what are (a) the tension TB in the cable that makes an angle of 40° with the vertical and (b) the tension TA in the horizontal cable?

why dont we add the Fg or W for when we solve for Ta? so why is it not -Ta + Tbx + (-Fg)? thank you.
