When hanging in equilibrium from C, the centre of mass will be vertically below C, i.e. it will be on the vertical. You need the angle between that line and CB.

Yes I thought as much, but I still ended up with the incorrect answer. So I know that the center of mass for the shape is (7.6, 3.7) but for some reason I keep getting the wrong answer and the mark scheme is very confusing.

Can't comment without seeing your working and the markscheme.
