1. The problem statement, all variables and given/known data

3. The attempt at a solution
This should be easy, but I'm tired and just can't do it. If anyone can point me in the right direction that'd be great. I tried making a FBD, and had the equations:
$$Tsin30^{\circ} - 752N = 0$$
$$344N - Tcos30^{\circ} = 0$$

But, that then gives me two different answers for T. So I'm lost.

note: the question asks you about the normal reaction force, doesn't that give u a hint?

first identify all forces acting on the ball, draw a force diagram and then balance them.
there should be 4 different forces acting on the ball

Haha, well that means I got the question wrong. Damn.

$$Tsin30^{\circ} - 752N = 0$$
$$344N - Tcos30^{\circ} = 0$$

?
