Answer:
x = 54
y = 114
Step-by-step explanation:
y = 114 because of the Corresponding Angles Theorem:
"If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent."
(x + 12) + y = 180
x + 12 + 114 = 180
x + (126 - 126) = (180 - 126)
Quick Check:
54 + 12 + 114 = 180 ✔
