Answer:
C. 
 and 
 
Step by step explanation:
Since we know that if a quadrilateral is inscribed inside of a circle then opposite angles of quadrilateral are supplementary. 
We can see that angle M is opposite angle of angle K. 




Therefore, measure of angle M is 113 degrees. 
We can see that angle N is opposite angle of angle L.




Therefore, measure of angle N is 61 degrees.
