Answer:
see below
Step-by-step explanation:
The basic formula for this chart is ...
Percentage = Base × Rate
Dividing by Base or Rate gives two other versions of the same relation:
Rate = Percentage/Base
Base = Percentage/Rate
These are summarized in the chart at the second attachment. Covering one of the cells in the chart tells you how that cell is computed. (See the formulas above.)

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:
Hence, the arc measurement x is 60°
