![\frac{\sin 104^{\circ}}{15}=\frac{\sin J}{12}\\\\\Rightarrow \sin J=\frac{\sin 104^{\circ}\times12}{15}\\\\\Rightarrow \sin J=\frac{0.97029572627\times12}{15}\\\\\Rightarrow \sin J=0.776236581016\\\\\Rightarrow J=\sin^{-1}(0.776236581016)=50.91728017\approx51{\circ}..............[\text{Using calculator}]](/tpl/images/0319/6067/a0c41.png)
