Answer:
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 squared is 9, so 9+9=18
now we have c but we arent done so now we find the square root,
. Which is
or 4.24.
