Answer:
I think the first one is 30.
I think the second one is 6
Step-by-step explanation:
<6 = <7 vertical angles
<1 = <4 vertical angles
if <6 = <4
then y is parallel to z because <1 = <7 alternate interior angles are equal
13x - 4 + 80 = 180⁰ (Sum of co interiar angles)
13x +76 = 180⁰
13x = 180⁰ - 76⁰
x = 104/13
x = 8
