The legs of an isosceles right triangle are 3 feet long. How long is the hypotenuse?

Answer 1

Explanation:

Since its isosceles right triangle, then 2 sides are going to be the same. There are 2 legs that are in any triangle, they give us 1 leg so now we know what the other leg is. Now the formula for finding hypotenuse is a2+b2=c2.

`3^(2)+3x^(2) =c^(2)` 3 squared is 9, so 9+9=18

now we have c but we arent done so now we find the square root,
`√(18)`. Which is
`3√(2)` or 4.24.
