The answer would be D.

To find the hypothenuse, you have to multiply by the square root of 2 and to find the side length is not necessary because it is the same length as the other side length

Answer:

D

Step-by-step explanation:

This is a 45 45 90 triangle

It is special because the sides are in a certain ratio of 1:1:[tex]\sqrt{2}[/tex]

[tex]\sqrt{2}[/tex] is the length of the hypotenuse and 1 is the length of the legs.

This means that the length of the legs are equal, so y=[tex]3\sqrt{2\\}[/tex]

If 1 part is [tex]3\sqrt{2\\}[/tex], we need to find what [tex]\sqrt{2}[/tex] is.

We can do that with [tex]3\sqrt{2\\}[/tex] *[tex]\sqrt{2}[/tex]
