The line is on 70/110. The angle is an obtuse angle (one larger than 90), so the correct answer would be 110. In the case that it is not clear whether the angle is obtuse or acute, find the place where 0 on the protractor sits on the line (on the side of the angle), and count up from there, on whatever circle (inner or outer) the 0 was on.
Answer: 110º
