Find the missing side of the right triangle

o-na [289]

Answer:

Step-by-step explanation:

Use the Pythagorean theorem:

$leg^2+leg^2=hypotenuse^2$

We have

$leg=3,\ leg=x,\ hypotenuse=\sqrt{10}$

Substitute:

$3^2+x^2=(\sqrt{10})^2$

$9+x^2=10$ <em>subtract 9 from both sides</em>

$9-9+x^2=10-9$

$x^2=1\to x=\sqrt1\\\\x=1$
