ANSWER


a=22\text{ inches}

Step-by-step explanation

We want to find the length of side a.

To do that, we apply trigonometric ratios:


\sin (\theta)=\frac{\text{opposite}}{\text{adjacent}}

Therefore:


\begin{gathered} \sin (30)=(a)/(44) \\ \Rightarrow a=44\cdot\sin (30) \\ a=22\text{ inches} \end{gathered}

That is the length of side a.
