Consider that lines u and vare parallel. Which equation models the relationship between the angles? What is the value of x?

Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.

Which means :

Thus, the value of x = 7.

Let's place 7 in the place of x and see if their value matches :

Thus, ∠12x - 4 = 80°

Thus, ∠10x + 10 = 80°

Since the value of these two angles are equal, we can conclude that we have found out the correct measure of each angle.

Therefore, the correct option is - (A) 12x - 4 = 10x + 10; x = 7
