Answer:
x = 5
Step-by-step explanation:
If the lines containing points A, B, C, D are parallel, then those two angles are equal because they would be corresponding angles. Therefore, you would set up this equation:
25x - 17 = 20x + 8
Subtract 20x from both sides
5x - 17 = 8
Add 17 to both sides
5x = 25
Divide both sides by 5
x = 5
