The tangent to the circumcircle of triangle WXY at X is drawn, and the line through W that is parallel to this tangent intersects at Z. If XY = 14 and $WX = 15$ find YZ.

XY  must be larger than WX !!! 

 

Here's why:

 

15 / 14  (14-YZ) / 15

 

If WX = 7, and XY = 14 then we have:

 

XZ / 7 = 7 / 14

 

XZ = 7/2

 

YZ = 14 - 7/2 = 21/2
