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
