\\ \tt\Rrightarrow cos\theta=(Base)/(Hypotenuse)


\\ \tt\Rrightarrow cos22=(12)/(x)


\\ \tt\Rrightarrow 12=xcos22


\\ \tt\Rrightarrow 12=0.92x


\\ \tt\Rrightarrow x=12/0.92


\\ \tt\Rrightarrow x=13.04

Using law of cosines:

Cos(angle) = adjacent/ hypotenuse


Cos(22) = 12/x

Rewrite to get:

X = 12/cos(22)

Simplify:

X = 12.9424

Round the answer as needed.
