Correct Answer: $x^2-1$

Solution : ${\operatorname{cosec} 39^{\circ}} = x$,
$ \frac{1}{\operatorname{cosec}^2 51^{\circ}} +\sin^239^{\circ} +\tan ^251^{\circ} -\frac{1}{\sin ^2 51^{\circ} \sec ^2 39^{\circ}}$
$= {\operatorname{sin}^2 51^{\circ}} +\sin^2(90^{\circ}-51^{\circ}) +\tan ^251^{\circ} -\frac{\cos ^2 39^{\circ}}{\sin^2(90^{\circ}-39^{\circ}) }$
$= {\operatorname{sin}^2 51^{\circ}} +\cos^251^{\circ} +\tan ^251^{\circ} -\frac{\cos ^2 39^{\circ}}{\cos ^2 39^{\circ} }$
$=1+\tan ^251^{\circ} -1$
$=\tan ^251^{\circ} $
$=\tan
