A) 90

1 answer:

6 0

We know that AB is perpendicular to CD. (that was given)

Perpendicular angles are 90 degrees because two straight lines (180) crossed make 4 90 degree angles.

180+180=360

90*4=360 See the similarities?

7x+6= 90 degrees

Subtract 6 on both sides.

7x=84

Divide both sides by 7.

x=12

"B" is the correct answer.

I hope this helps!
