Mechanics resolving
Is this the same:
Resolving in X direction: Pcosa+Qcos0-Rcos(90-B)=Pcosa+Q-RsinB
Because this is what the answer said (that they're equal) but when I inserted values which I kept constant for both calculations they came out different

I expect you've made a slip with your calculator - they should be the same. Are you in the right mode for angles (degrees/radians)?

just realised I'm in radians, that's probably why
That would explain it!
