Answer:
x= 30
The angles measure 80 degrees
Step-by-step explanation:
The two angles are corresponding angles and, when the lines are parallel, corresponding angles are equal.
2x+20 = 3x-10
Subtract 2x from each side
2x+20-2x = 3x-10-2x
20 = x-10
Add 10 from each side
20+10=x-10+10
30 = x
2x+20 = 2(30) +20 = 60+20 = 80
