Step-by-step explanation:

 Girls            Boys

     6                  7            <= reflects the 6:7 ratio mentioned in the problem

  =    

     18                 x

Cross multiply to determine x:  

6x = 7(18), or x = 7(3), or x = 21

There are 21 boys when we have 18 girls.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
