The law of sines can be expressed as seen below:


(a)/(\sin A)=(b)/(\sin B)=(c)/(\sin C)

Applying that to triangle we were given we obtain:


\begin{gathered} (3)/(\sin38)=(2.5)/(\sin x) \\ 3\cdot\sin x=2.5\cdot\sin 38 \\ \sin x=(2.5\cdot\sin 38)/(3) \\ x=\sin ^(-1)((2.5\cdot\sin 38)/(3))_{} \end{gathered}

So the first box is 2.5

The second box is 38

The third box is 3.
