\(I\) is the incenter of \(\triangle ABC.\). We have \(CE = 12\)\(AE = 9\), and \(AB = 12.\) Find \(BC.\)

From the angle bisector theorem, BC = 18.

Unfortunately, I don't think that is correct. Could you please reconsider? Thank you for your time.

Using the angle bisector theorem  we have: AE : EC = AB : BC

 

9 / 12 = 12 / BC          BC = 16
