Answer:

B

Explanation:

So we have a 45-45-90 triangle.

This is a special right triangle. In a 45-45-90 triangle, the side lengths are x, and the hypotenuse will be x√2

Since the hypotenuse is 3, we can set it equal to x√2 to solve for x. Therefore:

$x\sqrt2=3$

Divide both sides by √2:

$x=(3)/(\sqrt2)$

Rationalize:

$x=(3\sqrt2)/(2)$

Our answer is B.
