1. The problem statement, all variables and given/known data The resultant of the two forces has a magnitude of 650 lb. Determine the direction of the resultant and the magnitude of P. [See Attachment for Figure] 2. Relevant equations Well, I only know is R^2=Fx^2+Fy^2 im still confused by this problem 3. The attempt at a solution I tried using cosine law but it doesn't work well since the answer in the back is (a) 71.8 degrees and (b) 235lb Can someone help me? Very Much appreciated.
