The Attempt at a Solution

I feel like I am right and the computer is wrong, but I just wanted to check here first. I attached a picture of the problem and my answer.

This is how I solved the problem:

Fz=750sin(45)=530.33N
F’=750cos(45)=530.33N
Fx=F’cos(60)=256.165N
Fy=F’sin(60)=-459.28N

So my answer was: F=(256.165i-459.28j+530.33k)N and it says it's wrong. When i first submitted it, it said check signs, but i don't want to just guess at the signs because it takes off points for wrong answers, and i would like to know what I'm doing wrong.

It looks like you calculated the components correctly. If the computer says you are wrong, maybe it expects a different format from the one you used. I think you should your instructor for clarifications.
