Answer:
x = 5, z = 103
Explanation:
To solve for x:
11x + 22 = 6x + 47 ( Vertical angles are congruent/
have equal measure)
subtract 6x and 22 from both sides
5x = 25
x=5
11x + 22 + z = 180 (linear pairs are supplementary)
substitute 5 for x
11(5) + 22 + z = 180
55 + 22 + z = 180
77 + z = 180
-77 = -77
z = 103
