120°
140°
60°
can't be determined

Answer 1

the answer is 120 degrees because the answer up above doesnt make sense they only picked that because they didnt know but this is right because Adjacent angles are angles right next to eachother. a straight angle is equal to 180. If there are 2 angles on a straight angle that are adjacent to eachother, 180-60=120

Answer 2

Can't be determined.
