answer but it was marked incorrect.? Find an expression for, B, in terms of the prism's apex angle, a, and index of refraction, n.

I got sin^-1 (nsin(1/2)a).

Also, another question is:

A laboratory measurement finds that B = 51.5 for a prism that is shaped as an equilateral triangle. What is the prism's index of refraction?

Thanks.
