Answer
$\frac{1}{2}$ , $\frac{\sqrt{3}}{2}$ , $\frac{\sqrt{3}}{2}$ , and $\frac{1}{2}$.
Work Step by Step
By putting the values according to the trigonometric functions, we get:
$\sin {{30}^{\circ }}=\frac{1}{2}$
$\cos {{30}^{\circ }}=\frac{\sqrt{3}}{2}$
$\sin {{60}^{\circ }}=\frac{\sqrt{3}}{2}$
$\cos {{60}^{\circ }}=\frac{1}{2}$
