Answer: Option 'd' is correct.

Explanation:

Since we have given that

LMNO is a parallelogram.

Since we know that sum of adjacent angles is supplementary.

So, it becomes,


3x+8x-40=180^\circ\\\\11x-40=180^\circ\\\\11x=180+40\\\\11x=220^\circ\\\\x=(220)/(11)\\\\x=20^\circ

Hence, aoption 'd' is correct.
