Answer:
A
120
Explanation:
With all the parallel lines involved, the central figure is a parallelogram. These 4 sided figures have the odd property of having their opposite angles equal.
What that means, in plain English is that <NRL = <NML
Both of these angles = 120
Here's the cruncher. <NRL and <PRK are vertically opposite. They are therefore equal.
The answer to your question is 120 which is A
