+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 $\frac{XZ}{ZY}.$
+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
