An inequality is solved graphically as shown in the picture. The solution is marked in red. Choose the corresponding inequality.
\[ \cos{x} < \frac{1}{2} \] \[ x \in [ 0;2\pi ]\]
\[ \cos{x} \leq \frac{\sqrt{2}}{2} \] \[ x \in [ 0;2\pi ]\]
\[ \cos{x} < \frac{\sqrt{2}}{2} \] \[ x \in [ 0;2\pi ]\]
\[ \cos{x} \leq \frac{1}{2} \] \[ x \in [ 0;2\pi ]\]
