Answer 1

Do you have any ideas?

Answer 2

yes, at first I thought A, but now i'm not so sure

Answer 3

sorry I missed the part of the question were you made a guess. A is correct. 2 adjacent angles on a straight line always add up to 180 degrees, because a straight line is 180 degrees.

Thank you for clarifying that
