Question

Figure LMNO is a parallelogram. What is the value of x? a.8 b.10 c.13 d.20

Answer 1

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

LMNO is a parallelogram.

Since we know that sum of adjacent angles is supplementary.

So, it becomes,

$3x+8x-40=180^\circ\\\\11x-40=180^\circ\\\\11x=180+40\\\\11x=220^\circ\\\\x=\dfrac{220}{11}\\\\x=20^\circ$

Hence, aoption 'd' is correct.

Answer 2

I hope this helps you




M and N complimentary angle



3x+8x-40=180



11x=220


x=20
