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 :
[tex]XY^{2} =XZ^{2} +ZY^{2}[/tex]
Or,
[tex]ZY^{2} =(15\sqrt{2} )^{2} -15^{2}[/tex]
[tex]ZY^{2} =450-225=225[/tex]
Or ZY=15.
