It's a multiple choice question and the answer is 135, it doesn't give any other information just asks to find <AXB (A is the top left B is the top right)

If the diagram looked like that in the exam, I think it was a distractor.

Was the answer not 131? Or did you label your angles incorrectly? If not, then I shall check again :)

Okay so the number of degrees between the 305 line and the 80 line (clockwise) are 225 since 305-80 = 225.

Therefore we know that there is 360 degrees around a point so 360-225 =135
