Answer:Option C 15
Step-by-step explanation:
The distance from point Y to WX is represented by the line YZ.
Triangle XYZ is a right triangle with one of the leg and hypotenuse known .The other leg can be determined by the Pythagorean Theorem.
According to the theorem :
\(XY^{2} =XZ^{2} +ZY^{2}\)
Or,
\(ZY^{2} =(15\sqrt{2} )^{2} -15^{2}\)
\(ZY^{2} =450-225=225\)
Or ZY=15.
Option C 15
