12x2-3=21
this would be your equation because there are 12 tigers
Answer is A, y = 65
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
1. 2/7
2. 2/15
3. 5/24
