Answer:
z = 70
x = 6
Step-by-step explanation:
Z and 70 are vertical angles so they are equal
z = 70
12x+38 and 70 are supplementary angles so they form a straight line
This means they add to 180 degrees
12x+38 + 70 = 180
Combine like terms
12x+108 = 180
Subtract 108 from each side
12x+108-108= 180-108
12x = 72
Divide each side by 12
12x/12 = 72/12
x = 6
