AB (extended line) is parallel toDC

Step-by-step explanation:

•alternate interior angles are equal.

110=110

•also interior angles are equal to 180

110+70=180(linear pair)

Answer 2

Step-by-step explanation:

According to the figure we know that ∠BAC and ∠ACD are alternate angles So we get ∠BAC = ∠ACD = 110o We know that ∠BAC and ∠ACD are alternate angles when the transversal AC cuts CD and AB. Therefore, AB || CD.
