1. The problem statement, all variables and given/known data The Resultant of the system of forces shown is R = 425 j lbs. Determine the possible values of P and Θ. 2. Relevant equations R = F1 +F2+P 3. The attempt at a solution I ended up with two equations, one in the "i" direction and one in the "j" direction. I think you have to use the quadratic formula because I know that you will get two values for P and two values for Θ. Thanks!
