Since C is 61 degrees, A is 90 degrees because of the right angle, and B would be 29 degrees because you add 61 and 90 together and subtract that amount from 180.

Wait I'm sorry if this is what you aren't looking for-

600 sixth-graders were surveyed.

Step-by-step explanation:

Step 1; Assume x is the total number of sixth-graders that were surveyed. According to the given circle graph, 5% of the sixth-graders that were surveyed have birds as their pets. If x is the total number of sixth-graders surveyed then 5% of x equals 30. So

5% of x = 30.

5% equals $\frac{5}{100}$ = 0.05, so 5% = 0.05.

Step 2; If 0.05 x = 30, we can solve by keeping the unknown value on one side and keeping all the known values on one side.

x = $\frac{30}{0.05}$ = 600.

So 600 sixth-graders were surveyed.
