Answer:
Step-by-step explanation:
If the lines are parallel, then angles 1, 7, 3, and 5 are congruent because they are vertical/corresponding angles.
Therefore, they are all 113 degrees. For the rest of them, you just subtract from 180 to get 67. Therefore,
2 = 67 degrees
3 = 113 degrees
4 = 67 degrees
5 = 113 degrees
6 = 67 degrees
7 = 113 degrees
8 = 67 degrees
