Answer:
1) Alternate interior angles are congruent, hence x=115
2) Linear pairs add up to 180°, hence x=67
3) Alternate interior angles are congruent, hence x=89
4) Same side interior angles are supplementary, hence x=139
5) Linear pairs are supplementary, hence x=109
6) Alternate interior angles are congruent, hence x=88
7) Alternate interior angles are congruent, hence x=62
8) Same side interior angles are supplementary, hence x=74
Hope this helps!
