Answer:
60°
Explanation:
This questions tests our knowledge on arcs and arc measures.
-Arc measure is the angle that an arc makes with the circle's center.
-The arc measure is proportional to the arc.
#The sum of the 3 arcs is x+2x+3x=6x
Given a circle has 360°, the arc measurement x can be calculated as:
![[x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree](https://img.qammunity.org/2021/formulas/mathematics/middle-school/p93m1kj5xbz3wt9tyvcjea664uid170hba.png)
Hence, the arc measurement x is 60°
