Answer:
Step-by-step explanation:
The formula for this is
x° = [tex]\frac{1}{2}[/tex](major arc - minor arc)
The measure around the outside of a circle is 360°. We have the minor arc as 120°. So the major arc is 360 - 120 = 240. Fitting that into the formula:
x° = [tex]\frac{1}{2}[/tex](240 - 120)
x° = [tex]\frac{1}{2}[/tex](120)
x° = 60
