44
Assuming JM and LN are parallel, KMJ=MKN. MKN is part of a triangle where the other two values are defined (48 and 88). By subtracting these values from 180, we find the value of MKN is 44, which therefore is also the value of KMJ.
The answer to you question is c
The first one would be (-5,5) and the second one is (5,5) or 1.
I only see one question.
