I think the answer is a but I’m not for sure
Are a and b two points on a line
If they are you can use the distance formula
the relationship between the two angles is that they are supplementary angles because together they create a line that is 180 degrees. I might be wrong so please don't get mad if I am. I am 90 percent sure this is the answer though
Line p and q are not parallel, because the two given alternate interior angles are not congruent. (It’s B)
