1. The problem statement, all variables and given/known data find the magnitude and the angle that it makes with the positive x-axis? http://imageshack.us/photo/my-images/594/unledzmo.png/ 2. Relevant equations 3. The attempt at a solution The answer that I have is F= 179.37 at an angle of 91 degrees. Am I right? I took F1 and multiplied that by <cos60,sin60>, F2 multiplied that by <cos135,sin135>,F3 multiplied by <cos270,sin270> and then I added up all those vectors. then I used the Pythagorean theorem to get the magnitude then I took the inverse cosign of the x component of the resulting vector divided by the magnitude to get 91 degrees.
