Okay, I'm pretty confident that my first couple steps are right, though please do let me know if they're not. I'm not sure I've simplified enough and I'm not entirely sure what my next steps would be? Thanks in advance.

Idk if this is allowed here..Its straight forward "determine the resultant force acting on the hook in cartesian notation", I dont know if its my angles or if I am skipping a step but 490, 117, -266 sure aint it (per person's mastering) can anyone see and point out where I went wrong? Maybe I'm not doing my computing right or ive set up wrong. Ive been on this problem for 1.5 hours.. i dont know why. This is an online class so all I have is a textbook and dr Hanson videos, which are helpful so im confused on why im struggling so much? All im looking for is a point in the right direction. For now ill move onto the next problem but it is just the same so may post it as well 😅

I just need help identifying the sides please
