Answer
$\sin 750^{\circ}=\frac{1}{2}$,
$\cos 750^{\circ}=\frac{\sqrt 3}{2}$
$\tan 750^{\circ}=\frac{\sqrt 3}{3}$
Work Step by Step
$750^{\circ}=[750-(360\times2)]^{\circ}=30^{\circ}$
$30^{\circ}$ is coterminal with $750^{\circ}$.
$\implies \sin 750^{\circ}=\sin 30^{\circ}=\frac{1}{2}$,
$\cos 750^{\circ}=\cos 30^{\circ}=\frac{\sqrt 3}{2},$
$\tan 750^{\circ}=\tan 30^{\circ}=\frac{\sqrt 3}{3}$
