F1 = 120cos(60*) = 60
120sin(60*) = 103.9
x and y = (60,103.9)
F2 = -75cos(75*) or is it -75cos(15*)? = -19 or -72.4
75sin(75*) or 75sin(15*) = 72.4 or 19
x and y = (-19,72.4) or is is it (-72.4, 19)

Well I really have no idea where to begin with this one, if anyone could get me pointed in the right direction that would be much appreciated.
