Решите неравенство \(\sin{t}\le\frac{1}{2}.\)

\(-\frac{7\pi}{6}+2\pi{k}\le{t}\le{\frac{\pi}{6}}+2\pi{k}, k\in{Z}\)
\(\frac{\pi}{6}+2\pi{k}\le{t}\le{\frac{5\pi}{6}}+2\pi{k}, k\in{Z}\)
\(\frac{\pi}{6}+2\pi{k}\le{t}\le{\frac{11\pi}{6}}+2\pi{k}, k\in{Z}\)
\(-\frac{\pi}{6}+2\pi{k}\le{t}\le{\frac{\pi}{6}}+2\pi{k}, k\in{Z}\)
