I made a force diagram and wrote out the sums of the forces in the x and y then tried to solve for theta I got:

sumFx= -nsin theta=ma=mv^2/r

and

sumFy= -mg+ncos theta=0 --> n=mg/cos theta

then substituted n into the first

I ended up getting 89.6 degrees though...did I just make an algebra mistake or did I go about it the wrong way?
