\[\boxed{\mathbf{1.}\mathbf{64}}\]
Пояснение.
Решение.
\[\angle KZL = 20{^\circ};\ \ \angle LZM = 30{^\circ};\ \]
\[\angle KZM = 50{^\circ};\ \angle MZN = 75{^\circ};\ \]
\[\angle LZN = 105{^\circ};\]
\[\angle KZN = 115{^\circ};\ \angle NZO = 15{^\circ};\ \]
\[\angle OZT = 60{^\circ};\ \angle TZM = 130{^\circ};\ \]
\[\angle TZL = 160{^\circ};\]
\[\angle OZN = 15{^\circ};\ \angle OZM = 90{^\circ};\ \]
\[\angle OZL = 120{^\circ}.\]
\[\textbf{а)}\ \angle TZO < \angle TZM < \angle TZL.\]
\[\textbf{б)}\ \angle KZL < \angle KZM < \angle KZN <\]
\[< \angle KZO.\]
\[\textbf{в)}\ \angle OZN < \angle NZM < \angle OZM <\]
\[< \angle NZL < \angle OZL.\]
