Question

Pls help me i dont get it :(

Answer 1

7.alternate interior

x=64

8. same side interior

x=12

same side exterior

x=12

Answer 2

7. x = 64

8. x = 12

9. x = 12

Explanation:

7. alternate angle or opposite angle are equal

128 = 2x

x = 128 / 2

x = 64

8. interior angles = 180

180 = 72 + (7x + 24)

180 - 72 - 24 = 7x

x = 84 / 7

x = 12

9. same side angle = 180

180 = 65 + (11x - 17)

180 - 65 + 17 = 11x

x = 132 / 11

x = 12
