1. The problem statement, all variables and given/known data Given: >>Figure<< F1 = 250g, θ1 = 90° F2 = 150g, θ2 = 210° F3 = ?g, θ3 = ?° a. Calculate the values for F3 and θ3. b. Draw a diagram. 2. Relevant equations R = A + B R = A + B + C F = √(Fx)^2 + (Fy)^2 θ = TAN-1(Fy/Fx) 3. The attempt at a solution I've used to first and the third formula to solve for F3 and the last formula to try to solve for θ3 but my teacher told me that my answers were wrong. I'm just at a complete loss now on this problem. I've put up a link on top with the image that's part of the problem also. Could someone help me in the right direction? I don't want the answers but rather the proper way to go about solving this problem?
