31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
The rule for the angle formed outside of circle by intersection show below is given by:
Angle formed outside=1/2(difference of intercepted arcs)
∠ACE=1/2(AE-BD)
∠ACE=53°
AE=233°
BD=x
Hence the formula for obtaining BD will be:
53=1/2(233-x)
The correct answer is A
I think that it might be "c" but I am not sure but hey it is worth a shot sorry if I am wrong!
600 = 360 + 240
In unit circle, (x,y) = (cos(240), sin(240) ) = (-sqrt(3) / 2, -1/2)
