Hi,

a) your equation can have more thhan one solution
    so there is not always one value
b)

x/. Solve[Tan[45*Degree]*x + (Sin[108.25718805973634]*
             (-Sqrt[(-0.425185)^2 + 0.843815^2]))/
          Sin[135*Degree] == 0, x]

will work.

c) we have answered this several million times.

Regards
   Jens
