50/10 or 50/5, and I think maybe 50/1 I'm not sure
The intersecting chord theorem says
![AY \cdot BY = CY \cdot DY](https://tex.z-dn.net/?f=%20AY%20%5Ccdot%20BY%20%3D%20CY%20%5Ccdot%20DY%20)
![AY = \dfrac{ CY \cdot DY}{BY} = \dfrac{6 \cdot 12}{9} = 8](https://tex.z-dn.net/?f=%20AY%20%3D%20%5Cdfrac%7B%20CY%20%5Ccdot%20DY%7D%7BBY%7D%20%3D%20%5Cdfrac%7B6%20%5Ccdot%2012%7D%7B9%7D%20%3D%208)
![AB = AY + BY = 8 + 9 = 17](https://tex.z-dn.net/?f=AB%20%3D%20AY%20%2B%20BY%20%3D%208%20%2B%209%20%3D%2017)
