The student did not make the opening of each arc drawn from S and T greater than half the length of the line ST. When drawing a perpendicular bisector, the arcs should go past the center of the line segment.
If this is using transversals, and they are in fact a linear pair, then the answer would be 180-113= 67
If its not a transversal, let me know!
