Answer 1

The right answer is 15

Answer 2

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.
