Answer:
6
Step-by-step explanation:
Because if two parallel lines are intersect by a transversal then alternate exterior angles are equal.
so, picture where the 3x is as 1 and where the D is 2. Under the 3x (the angle under it) will be 3 and the angle under D is 4.
Now lets number the next angles. E will be 6 and the angle before it will be 5. where the 6x is will be 7 and next to it will be 8. So basically number all the angles from up to down.
So, basically go get 6 as your answer, '2' and '7' will always be the same number for the answer. Iits really confusing i know, but just search Transversal parallel lines, and I'm sure more will come up (if you want to learn more, its up to you)
