Three forces act simultaneously on point J. One force is 20.0 N north; the second is 20.0 N west; the third is 20.0 N 60° east of north. Determine the magnitude and direction of the resultant force.
I need help with this problem. I know you can figure this out by putting it on a graph and adding the cordinates but I cant find the cordinates of the 60º one. The north one is (20,0) and the west is (-20,0).

Are you familiar with vector components?

x = 20cos60
y = 20sin60

(x,y) for the third force.
