HELP DUE TUESDAY (last day of school)
please solve for x and y in the diagrams below:

x = 10°
y = 112°
Step-by-step explanation:
From the definition of supplementary angles,
68° + y = 180° ---> y = 180° - 68° = 112°
From the definition of vertical angles,
(4x - 2) + 30 = 68
4x - 2 = 68 - 30 = 38
4x = 40
x = 10
Answer:
y+68=180(being straight angle)
y=180-68
y=112
4x-2=30
4x=28
x=7
