Because the cone is being held up, I said mg=2f_{y}, where f is the friction force, so mg=2uNcos(x) (where x=theta), and I got N=mg/(2ucos(x)).

The cone also isn't moving from side to side, so I said N_{x}=f_{x}, so fsin(x)= uNsin(x)=Ncos(x), so u=cot(x), then I replace u in my first equation to get N=mg*tan(x)/(2cos(x))...

I have a feeling this is wrong though. Help please.
