\[\angle MKS = 107{^\circ};\]
\[\angle EKP = 95{^\circ};\]
\[\angle MKP = 180{^\circ} - развернутый.\]
\[\angle SKP = \angle MKP - \angle MKS =\]
\[= 180{^\circ} - 107{^\circ} = 73{^\circ}.\]
\[\angle EKS = \angle EKP - \angle SKP =\]
\[= 95{^\circ} - 73{^\circ} = 22{^\circ}.\]
\[Ответ:\ 22{^\circ}.\]
