BRAINLIST RIGHT ANSWER RN

Find the value of x that makes ABCD a parallelogram.

Since a parallelogram is total measurement is= 180 then

A+B+C+D=360

70+(x+40)+70+(x+40)=360

= 140+(x+40)+(x+40)=360

(x+40)+(x+40)=360-140=120

(x+40)+(x+40)=120

So lets give x a random number to see if the value is correct

X=20

(20+40)+(20+40)=

=60+60=120

So x =20

But i dont see that option in your question

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
