\[\angle AOK = 90{^\circ} - прямой;\ \ \]
\[\angle COK = 180{^\circ} - развернутый.\]
\[\angle POC = 54{^\circ}.\]
\[\angle AOP = 180{^\circ} - 90{^\circ} - 54{^\circ} =\]
\[= 36{^\circ}.\]

\[1)\ x + 34 = 76\]
\[x = 76 - 34\]
\[x = 42.\]
\[Ответ:42.\]
\[2)\ 238 + y = 416\]
\[y = 416 - 238\]
\[y = 178.\]
\[Ответ:178.\]
\[3)\ a + 157 = 324\]
\[a = 324 - 157\]
\[a = 167.\]
\[Ответ:1\]
\[4)\ 356 + b = 782\]
\[b = 782 - 356\]
\[b = 426.\]
\[Ответ:426.\]
\[5)\ x - 546 = 216\]
\[x = 216 + 546\]
\[x = 762.\]
\[Ответ:762.\]
\[6)\ 206 - y = 139\]
\[y = 206 - 139\]
\[y = 67.\]
\[Ответ:67.\]
\[7)\ 895 - a = 513\]
\[a = 895 - 513\]
\[a = 382.\]
\[Ответ:382.\]
\[8)\ m - 2092 = 1067\]
\[m = 1067 + 2092\]
\[m = 3159.\]
\[Ответ:3159.\]
