In the figure, d, e, and f are parallel lines. What is the value of x? Enter your answer in the box.

In the given figure, can you conclude r || s?

• The lines are parallel because the given angles are same-side interior angles and their sum is 180°.

• The lines are parallel because the given angels are alternate interior and they are supplementary.

• The lines are not parallel because the given angles are corresponding angles and they do not have equal angle measures.

• There is not enough information.
