Essentially, you are solving the equation FullSimplify[Solve[a - Cos[t] - Sqrt[R^2 - Sin[t]^2] == x, t]] where x = 2 n rhs/d is a constant multiple of your right-hand side, rhs, t is theta_4, and a = R + 2/(c - 1) + 1. This is, of course, trivial. I expect that Solve struggles with your expression because of the length and/or complexity of rhs. To me, using \[UnderBracket] makes your input expression unreadable. Only an engineer would work with such expressions! Personally, I like using subscripted expressions in Mathematica. They are not without their difficulties and subtleties -- but are preferable to using \[UnderBracket].
