What is the valuee of x

The value of x in this equation is 0. Just kidding bruv, you need an attachment. The value of the variable x varies within each equation. Such as, -5x+9=2(x+7), x could be anything, but you'd have to solve some of the other parts first.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

i think it would be 42cm
