The graph shows percentages of sales made by various divisions of a company in one year. What are the angles formed by the segments for each division? What are the missing percentages? Explain how you were able to determine each percentage.

Answer:
Division C = 9%
Division E = 10%
Step-by-step explanation:
From the pie chart attached,
Let the missing percentage of division C and E are c% and e% respectively.
Since, division B + division C + division D = 50%
[Divisions on one half of the circle]
23% + c% + 18% = 50%
41% + c% = 50%
c = 50 - 41
c = 9%
Similarly, division A + division F + division E = 50%
27 + 13 + e = 50
40 + e = 50
e = 10%
