1. The problem statement, all variables and given/known data see attachment 2. Relevant equations see attachment 3. The attempt at a solution I understand everything about the problem except how to determine the angle P makes with the new horizontal axis (parallel with F)--see diagram under primary one... so that I can sum the forces up and answer the problem. My geometry is somewhat rusty and I'm not exactly sure what geometric property makes the angle 45. Any help is appreciated.
