+92 Circle A and Circle B intersect at two points P and Q. A common tangent line of the two circles touches circle A and circle B at points X and Y respectively. XY and the extension of PQ intersect at Z. We know the radius of circle A is 7, the radius of circle B is 24, and AB=25. Find XZZY.
+1641 Circle A and Circle B intersect at two points P and Q. A common tangent line of the two circles touches circle A and circle B at points X and Y respectively. XY and the extension of PQ intersect at Z. We know the radius of circle A is 7, the radius of circle B is 24, and AB = 25. Find XZ / ZY.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
XZ ≅ ZY ==> XZ / ZY = 1
