The measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given. 
[tex]\overset{\LARGE{\frown}}{AB}[/tex] = 49

To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted  D. 

[tex]\overset{\LARGE{\frown}}{BDC}[/tex] = 360 - 49 - 107 = 204
[tex]\overset{\LARGE{\frown}}{ABC}[/tex] = [tex]\overset{\LARGE{\frown}}{BDC}[/tex] + [tex]\overset{\LARGE{\frown}}{AB}[/tex] 

Arc(ABC) = 204 + 49 = 253

Arc(BAC) = Arc(BC) + Arc(AB)
Arc(BAC) = 107 + 49
Arc(BAC) = 156

Arc(ACB) = 107 + 204 = 311
