I would subtract 1sin(Θ) from each side of the equation.
The equation would then say that 2sin(Θ) = -1 .
I would only have to find angles whose sin is -1/2 ,
and those would be my solutions.

   3sinΘ = sinΘ - 1
3sinΘ - sinΘ = sinΘ - sinΘ - 1
   2sinΘ = -1
      2sin    2sin
       Θ = -2.864934497
