Question

Find the missing side of the right triangle

Answer 1

1

Explanation:

Use the Pythagorean theorem:

`leg^2+leg^2=hypotenuse^2`

We have

`leg=3,\ leg=x,\ hypotenuse=√(10)`

Substitute:

`3^2+x^2=(√(10))^2`

`9+x^2=10` subtract 9 from both sides

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

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