Question

Need help asap plzzz with steps

Answer 1

Explanation:

7. x + 78 = 70

x = -8

corresponding angles

8. 13x = 5 + 12x

x = 5

alt. ext. angles

9. 56x - 2 = 110

56x = 112

x = 2

vertical angles

10. 26x + 5 = 135

26x = 130

x = 5

alt. int. angles

11. x + 110 = 100

x = -10

vertical angles

12. 12x + 4 = 13x - 4

-x = -8

x = 8

alt. ext. angles
