Answer:
Step-by-step explanation:
Whatever answer you have for 9, I am assuming that's where you calculated the 's'. To find the diagonal side of a square, simply multiply the length of the side by the square root of 2.
So if 's' value was supposedly 5. Then diagonal value of x is [tex]5\sqrt{2}[/tex].
The reason we multiply by square root 2 is because we derive the formula using pythagorean formula.
s² + s² = diagonal²
diagonal = √(s² + s²)
diagonal = √(2 * s²)
diagonal = s√2
Plug in value of 's' value you got up above and you have your answer!
