Please help Z and Y

Answer:
10=Z and 10=Y
Step-by-step explanation:
since it is a 45, 45, 90 triangle
both Z and Y will be the same length
the hypotenuse has a length of [tex]x\sqrt{2}[/tex] with x being the length of the legs
Since the length of this triangle's hypotenuse is [tex]10\sqrt{2}[/tex] the side length would be 10
Hope that helps :)
