Because the shape is a parallelogram, LM and PN have the same length.
Therefore, y+8=5y
8=4y
y=2
Parallelograms have a total angle measure of 360 degrees. Opposite angles have the same measure, and angle MLP and LPN add up to 180 degrees.
Therefore, 2x-8 + 4x=180
6x-8=180
6x=188
x=31.3
This means that the correct option is A.
