I'm currently studying for midterms next week and this problem has stumped me for the last 2 hours.

Resolve the forces along x and y(say they are Fx and Fy), then put Fy=0 to get magnitude of F2 and then the resultant force is Fx.

one question? why the y component?

Because the resultant force is only along x direction. So the y component is 0.

what does that mean?

Have you done any vector algebra courses?

How have they only run into problems now if they haven't. All statics is is vectors

What are the things you have tried?

I get it now.

Fx=Rx

Fy=0

Solving Fy will solve Fx and give out the resultant and the y component is that it is the only positive answer that aligns well to the FBD .
