We can notice that the balance beam has in one side 7 balls and in the other one 5 balls and a square
The balance beam is balenced

- x+5 = 7 substract five from each side
- x+5-5 = 7-5
- x = 2
The solution is 2
C fits perfectly what we prooved
With the help of theorems involving circles, assuming that arc ABC is a central angle (meaning both legs of the angle start from the centerpoint), the measure of the inscribed angle is twice that of the central angle. Thus, arc AC is equal to 2*40°= 80°.
Answer:
B. 19
