Answer: y=40
Step-by-step explanation:
The 2 angles are the same because there is a transverse line through 2 parallel lines and they are same side consecutives
2x+30 = x+85 >subtract x from both sides
x+30 = 85 >subtract 30 from both sides
x=55
Angle = x+85 >substitute x=55
Angle = 55+85
Angle = 140
That angle and y added = 180 because they create a line
Angle + y = 180
140 + y = 180
y=40
