Answer:
Step-by-step explanation:
The angles with measure of 66 and x are consecutive interior angles and therefore supplementary:
- x + 66 = 180
- x = 180 - 66
- x = 114
The angles x and 4y - 6 are alternate interior angles and therefore congruent:
- x = 4y - 6
- 114 = 4y - 6
- 4y = 114 + 6
- 4y = 120
- y = 120/4
- y = 30
