Mathematics

Answer:

\dfrac{1}{2}

Step-by-step explanation:

If 180^{\circ} then angle x is in the III quadrant.

Since \tan x=\sqrt{3}, then x=240^{\circ}\ [180^{\circ}+60^{\circ}] (we get angle in the III quadrant)

Consider \sin (x-210^{\circ}).

If x=240^{\circ}, then

\sin (240^{\circ}-210^{\circ})\\ \\=\sin 30^{\circ}\\ \\=\dfrac{1}{2}
