Answer:

arc XY = 110°

Step-by-step explanation:

arc XY = 162 - 52

arc XY = 110°

Margaret [11]

The percentage would be the number in carpooling over the total number of employees in the company.

Number in carpooling/Total number in company

Convert that to a percentage by multiplying by 100.
16.9%
