Explanation:

Step1: Apply Pythagorean theorem

For a right - triangle, \(a^{2}+b^{2}=c^{2}\), where \(c\) is the hypotenuse. Let the unknown side be \(x\). Assume \(\sqrt{5}\) is the hypotenuse (\(c = \sqrt{5}\)) and one of the legs \(a = 2\). Then \(x^{2}+2^{2}=(\sqrt{5})^{2}\).

Step2: Solve for \(x\)
