SOMEONE PLEASE HELP! I need to find the value of X and round to the nearest tenth

We know that the sine of an angle is equal to the opposite of this angle (which is 20) divided by the hypotenuse (30). This translates to sin(x)=\frac{20}{30}

To solve this equation, we first have to get x to one of the equation's sides. To accomplish this, we will apply sine inverse to both ends.

sin^{-1}(sin(x))=sin^{-1}(\frac{20}{30} )

Remember that sin^{-1}(sin(\theta))=\theta

x=sin^{-1}(\frac{20}{30} )

Simplify using your calculator and that will give us x=41.8\°
