Answer:
x = 65/3
Step-by-step explanation:
These angles are corresponding angles, Corresponding angles are equal if the lines are parallel
Assuming the lines are parallel
6x-20 = 3x+45
Subtract 3x from each side
6x-3x-20 = 3x-3x+45
3x-20 = 45
Add 20 to each side
3x-20+20 = 45+20
3x = 65
Divide by 3
3x/3 = 65/3
x = 65/3
