I don't know!
r became the hypotenuse, due to the angles in a straight line being 180, by subtracting the angle found in the original question, we can find the internal slant angle.
The answer doesn't need any trig functions. Like you said, h^2 = r^2 - R^2 (R is what I defined as 2*pi*r-2*pi*r*a). Substitute that for R in the previous expression, solve for h and you should come up with what I had in my previous post (unless I screwed up with the algebra.)
Or wait, are we talking about finding h or the slant angle? I forgot what's going on here lol
