Ответ:
[tex]112^{\circ}[/tex]
Объяснение:
[tex]ON=OK=r \Rightarrow \triangle ONK-[/tex]
– равнобедренный ⇒ ∠NKO = ∠KNO = 56°.
[tex]\angle MON=180^{\circ}-\angle NOK, \ \angle NOK=180^{\circ}-(\angle NKO+\angle KNO) \Rightarrow[/tex]
[tex]\Rightarrow \angle MON=\angle NKO+\angle KNO \Rightarrow \angle MON=56^{\circ}+56^{\circ}=112^{\circ};[/tex]
