1. The problem statement, all variables and given/known data http://img843.imageshack.us/img843/5370/helpxd.jpg [Broken] 2. Relevant equations Sin law 3. The attempt at a solution I got to: F1/sin(105) = F1u/sin(45) = F1v/sin(30) I get F1u = - 219 and F1v = 254.5.... It says it is wrong, not sure what I did.
