You currently have:
Sine(θ) = 0.9056
Simply apply inverse-sine to both sides to make the angle the "sugject" of this equation. This is commonly shown as "asin"
θ = asin(0.9056)
This is not something are expected to work out by hand, so I hope you have a calculator handy.
Note on most scientific calculators I see, the inverse of Sine is shown as Sine-1.
θ = Sine-1(0.9056) = 64.9°
