diagonals ( n is the number of sides )
we know that
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
So
m∠O=m∠M
m∠L=m∠N
m∠O+m∠L=
Step 
Find the value of x

Step 
Find the value of angle L
m∠L
m∠L
m∠L
Remember that
m∠N=m∠L
m∠N=
therefore
the answer is
the measure of the angle N is equal to
