HELP ASAPPPPPPPPPPP!!!

Answer 1

Answer:

Step-by-step 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, $\sqrt{18}$. Which is $3\sqrt{2}$ or 4.24.
