Given:
KLMN is a parallelogram
[tex]m\angle N=67^o[/tex]
We know that the sum of adjacents angles of a parallelogram is equal to 180 degrees.
[tex]m\angle N\text{ and m}\angle M\text{ are adjacent angles.}[/tex][tex]m\angle N+m\angle M=180^o[/tex]
[tex]\text{ Substitute }m\angle N=67^o,\text{ we get}[/tex]
[tex]67^o+m\angle M=180^o[/tex]
[tex]m\angle M=180^o-67^o[/tex]
[tex]m\angle M=113^o[/tex]
Hence the answer is
[tex]m\angle M=113^o[/tex]
