We know that, In a Right Angled Triangle :
✿ (Hypotenuse)² = (First Leg)² + (Second Leg)²
From the Diagram :
✿ Hypotenuse = x
✿ First Leg [tex]\bf{= 2\sqrt{3}}[/tex]
✿ Second Leg [tex]\bf{= \sqrt{6}}[/tex]
[tex]\bf{\implies x^2 = (2\sqrt{3})^2 + (\sqrt{6})^2}[/tex]
[tex]\bf{\implies x^2 = 12 + 6}[/tex]
[tex]\bf{\implies x^2 = 18}[/tex]
[tex]\bf{\implies x = 3\sqrt{2}}[/tex]
