ANSWER


\theta =73.2 \degree


EXPLANATION

We use the sine rule to obtain,


( \sin( \theta) )/(4) = ( \sin(50 \degree) )/(3.2)

We multiply both sides by 4 to obtain,



\sin( \theta) = ( \sin(50 \degree) )/(3.2) * 4
We take the inverse sine of both sides to get,



\theta = \sin ^( - 1) (0.9576)

\theta =73.2
to the nearest tenth.
