## Homework Statement

Hello everyone,

I have a few questions regarding the problem below.

1. I did the process for solving γ correct however I took the 60° angle instead of the 120° angle. The below solution states that γ>90°. Why must is be greater, than 90°, and when would it have been smaller?

2. I got a big confused when solving for the projected portion of the triangle. What I did initially was solve for the hypotenuse of the projection which I thought would be

F'=450sin(45°), and just use that F' to find the x, and y components, however that was completely wrong it seems.
