1. Problem Description

We are given a 30-60-90 triangle with the side opposite the 60 degree angle having length 6\sqrt{6}. We want to find the length of the hypotenuse xx.

2. Solution Steps

In a 30-60-90 triangle, the sides are in the ratio 1:3:21:\sqrt{3}:2, where the side opposite the 30 degree angle is 1, the side opposite the 60 degree angle is 3\sqrt{3}, and the hypotenuse is

2. Let the side opposite the 30 degree angle be $a$. Then the side opposite the 60 degree angle is $a\sqrt{3}$, and the hypotenuse is $2a$.

We are given that the side opposite the 60 degree angle is 6\sqrt{6}. Therefore,
a3=6a\sqrt{3} = \sqrt{6}
a=63=63=2a = \frac{\sqrt{6}}{\sqrt{3}} = \sqrt{\frac{6}{3}} = \sqrt{2}
The hypotenuse xx is 2a=222a = 2\sqrt{2}.

3. Final Answer

x=22x = 2\sqrt{2}
