Answer:
60°
Step-by-step 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:
[tex][x+2x+3x]=360\textdegree\\\\6x=360\textdegree\\\\x=60\textdegree[/tex]
Hence, the arc measurement x is 60°
