Answer:
x = 10
Explanation:
This is a parallel line cut by a transversal.
The two angles are corresponding angles. Therefore, they are equal to each other.
6x+8 = 68 >> subtract 8 from both sides
6x = 60 >> divide both sides by 6 to get x alone
x = 10
you can check by substituting 10 as x and see if 6x+8 is equal to 68 which it is
