The measure of the arc AC is proportional to the percentage that coresponds to the regions between A and B and between B and C (Vit. B and Vit. C).
Since the percentage that corresponds to Vitamin B is 22% and the percentage that corresponds to Vitamin C is 24%, the total percentage for both vitamins is 46%.
Then, the arc AC subtends a measure that is equal to 46% of the complete circle. The complete circle has a measure of 360º. Then, find what 46% of 360º is equal to:
[tex]\frac{46\times360}{100}=165.6[/tex]
Therefore, the measure of arc AC is 165.6º.
