Fatima will decorate the room with groups of 3 balloons. which package of balloons should she buy sot there are no left overs: 16,42, or 128 balloons? use divisibility rules to prove your answer.

A. 32°

Step-by-step explanation: how we find the measure of angle ACB is by taking the angle of arch BA and subtracting it by the angle of arch XA. then taking that number and dividing it by two.

so we know the angle of arch BA is 176° but we need to find arch XA. the angle of the arch XA is two times the measure of angle B

56 × 2 = 112

angle arch XA is 112°

now we plug both of those in for what i described earlier:

176 - 112 = 64

64 ÷ 2 = 32

angle ACB = 32°

hope this helped! :)
