Answer:
x = 29
y = 110°
Step-by-step explanation:
y° = (3x + 23)° => corresponding angles are congruent)
(2x + 12)° + y° = 180° => linear pair
Thus:
(2x + 12)° + (3x + 23)° = 180° => substitution
2x + 12 + 3x + 23 = 180
Add like terms
5x + 35 = 180
5x = 180 - 35
5x = 145
x = 145/5
x = 29
✔️y = (3x + 23)°
Plug in the value of x
y = 3(29) + 23
y = 110°
