Look at the diagram and choose the correct answer.

**(A)** **(B)** AB is not parallel to CD

**(C)** x = **(D)** Both **(B)** and **(C) **

**(E) **Both** (A) **and** (C)**

We can see that there are two angles in the diagram each of and these are corresponding angles.

Therefore, .

Because , x **(Alternate interior angles are equal if lines are parallel)**

x

Hence, the answer is **(E)**.
