Answer:
![x=2\sqrt{5}](https://tex.z-dn.net/?f=x%3D2%5Csqrt%7B5%7D)
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a
by
shape. We'll use Pythagorean Theorem to find the diagonal.
![a^2+b^2=c^2\\\sqrt{10}^2+ \sqrt{10}^2=x^2\\10+10=x^2\\20=x^2\\\sqrt{20}=x\\\sqrt{4*5}=x\\ 2\sqrt{5}=x](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2%5C%5C%5Csqrt%7B10%7D%5E2%2B%20%5Csqrt%7B10%7D%5E2%3Dx%5E2%5C%5C10%2B10%3Dx%5E2%5C%5C20%3Dx%5E2%5C%5C%5Csqrt%7B20%7D%3Dx%5C%5C%5Csqrt%7B4%2A5%7D%3Dx%5C%5C%202%5Csqrt%7B5%7D%3Dx)
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
