In $$\triangle ABC$$, $$\angle B= {90}^{\circ}$$, $$\sin{C} = \dfrac{3}{5}$$, then $$\cos{A} =$$ ______

In the following figure $$AB \perp BC$$ and $$\angle ACB = 30^\circ$$, given $$BC = \sqrt{300}\ m$$. The length of $$AB$$ is

If $$\sin \theta = \dfrac {3}{5}$$, then the value of $$\text{cosec}\, \theta$$ is

The value of $$2\sin 30^{\circ} \cos 30^{\circ}$$ is equal to

The value of $$\dfrac {\sin 27^{\circ}}{\cos 63^{\circ}}$$ is

The value of $$cosec^{2} 60^{\circ} - 1$$ is equal to

If $$x = \dfrac {2\tan 30^{\circ}}{1 - \tan^{2} 30^{\circ}}$$, then the value of $$x$$ is:

If $$\cos x = \sin 43^{\circ}$$, then the value of $$x$$ is

The value of $$\sin^{2} 60^{\circ} + \cos^{2} 60^{\circ}$$ is equal to

If $$sin^2 (3x + 45) + cos^2 (2x + 60) = 1$$ then $$x =$$ ...............
