(C) We know the trigonometric identity for complementary angles: $\sin(90^{\circ} - A) = \cos A$ and $\cos(90^{\circ} - A) = \sin A$.Given the equation: $\sin 70^{\circ} = \cos 	heta$.We can rewrite $\sin 70^{\circ}$ as $\cos(90^{\circ} - 70^{\circ})$.Therefore,$\cos(90^{\circ} - 70^{\circ}) = \cos 	heta$.This simplifies to $\cos 20^{\circ} = \cos 	heta$.By comparing the angles,we get $	heta = 20^{\circ}$.

If $\sin 70^{\circ} = \cos \theta$,then $\theta = \ldots \ldots \ldots \ldots$ (in $^{\circ}$)
