Central angles and the arcs they subtend have the same measure, so that


Answer:

Step-by-step explanation:
Step-by-step explanation:

Convert the mixed numbers above to improper fractions. Thus:

In order to simplify the fractions above, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that -2/3 to -3/2. Hence,
