ANSWER
Here, ABCD is a parallelogram.
We know that in parallelogram adjacent angles are supplementary.
⇒ ∠A+∠B=180
o
⇒ 4x+20
o
+7y=180
o
⇒ 4x+7y=160
o
------ ( 1 )
⇒ ∠A+∠D=180
o
⇒ 4x+20
o
+6x+3y−8=180
o
⇒ 10x+3y=168
o
----- ( 2 )
No multiplying equation ( 1 ) by 10 and equation ( 2 ) by 4 we get,
⇒ 40x+70y=1600
o
----- ( 3 )
⇒ 40x+12y=672
o
----- ( 4 )
Now subtracting equation ( 4 ) from equation ( 3 ) we get,
⇒ y=16
o
Substituting value of y in equation ( 1 )
⇒ 4x+7(16
o
)=160
o
⇒ 4x=48
o
∴ x=12
o
