An equation is solved graphically as shown in the picture. The solution is marked in red. Choose the corresponding equation.
\[ \mathrm{cotg}\,{x} = -\frac{\sqrt{3}}{3} \]
\[ x \in ( -\pi ;2\pi)\]
\[ \mathrm{cotg}\,{x} = -\frac{1}{2} \]
\[ x \in (-\pi ;2\pi )\]
\[ \mathrm{tg}\,{x} = -\frac{\sqrt{3}}{2} \]
\[ x \in ( -\pi ;2\pi)\]
\[ \mathrm{tg}\,{x} = -\frac{1}{2} \]
\[ x \in ( -\pi ;2\pi)\]
