Answer 2

Answer:

AB equal To CD

Step-by-step explanation:

As We for finding parallel lines equal we must see whether the inside Angles equal or not so

1. 105+x=180
2. x=180-105=75
3. so y will be 75
4. as we know opposite interior and exterior angle are equal
5. angle y equal to angle x
6. now angle E so as we know Sum of Two linear angle is 180
7. 75+x=180
8. x=180-75=105
9. thus angle E equal to angle x
10. therefore all opposite angles equal so it us parallel
