Question

Point y is on a circle and point y lies outside the circle such that py is tangent to the circle. Point a is on the circle such that segment pa meets the circle again at point b. If pa=15 and py=9, then what is ab?

Answer 1

@FIt -->

I think there's a typo here --> Point y is on a circle and point y lies outside the circle

Point Y cannot be simultaneously on the circle and outside the circle.

Please post a diagram and copy the question exactly as it appears in your problem source.

Thanks.
