1. The problem statement, all variables and given/known data See the attachment 2. Relevant equations 3. The attempt at a solution I am pretty lost where to start... no relationship pops out at me to help in finding the components of the PR and QR to find the magnitude of QR and PR. I know lots of angles, but don't see how I can quite relate them to the 250 N force. If anyone could help me pointed in the right direction, it would be appreciated.
