Since $ \ x = 2 \sin \theta \ $, it follows that $$ \sin \theta = \displaystyle{ x \over 2} = \displaystyle{ opposite \over hypotenuse } $$ and $$ \theta = \arcsin \Big(\displaystyle \frac{x}{2} \Big) $$ Using the given right triangle and the Pythagorean Theorem, we can determine any trig value of $ \theta $.
