I am trying to figure out how you find the direction and magnitude of a resultant force? Any info on this, would be very helpful... Thank you

Since you're using a cartesian co-ordinate system (there will always be useful 90 degree angles), you need to apply trigonometric laws and pythagoras' theorem.

If you gave a sample question that you're having trouble with and show an attempt at finding the answer, then I can help you identify where you are going wrong.
