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].
Cheers,
Paul
