What is the value of x?

a.8
b.10
c.13
d.20

Answer 1

I hope this helps you




M and N complimentary angle



3x+8x-40=180



11x=220


x=20

Answer 2

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.
