In parallelogram JKLM, adjacent angles sum to 180&deg;.<br><br>
&bull; \( \angle \)JML = 65&deg; (given or found from previous parts).<br>
&bull; \( \angle \)MJK is adjacent to \( \angle \)JML (they share side JM).<br>
&bull; Adjacent angles in a parallelogram are supplementary: 65&deg; + \( \angle \)MJK = 180&deg;.<br>
&bull; \( \angle \)MJK = 180&deg; &minus; 65&deg; = 115&deg;.<br><br>
Final Answer: 115&deg;
