Answer:

1

Step-by-step explanation:

Use the Pythagorean theorem:

[tex]leg^2+leg^2=hypotenuse^2[/tex]

We have

[tex]leg=3,\ leg=x,\ hypotenuse=\sqrt{10}[/tex]

Substitute:

[tex]3^2+x^2=(\sqrt{10})^2[/tex]

[tex]9+x^2=10[/tex]             subtract 9 from both sides

[tex]9-9+x^2=10-9[/tex]

[tex]x^2=1\to x=\sqrt1\\\\x=1[/tex]
