Answer 2

AD and BC are parallel lines. And BA is a transversal. Now, as a rule, Interior angles (angles inside the parallel lines) on the same side of the transversal are supplementary.

Therefore, angle ABC plus angle BAD is equal to 180 degrees.

As angle ABC = 80 degrees, angle BAD = 100 degrees.
That is, x = 100 degrees
