Mathematics

$\frac{2}{3} \sqrt{3}$

Step-by-step explanation:

We know this triangle has angles 30, 60, and 90 degrees. Triangles with these angles have a special relationship on the sides.

The side opposite to the 90 degree angle is 2 times of x.

The side opposite to the 60 degree angle is $\sqrt{3}$ multiplied x.

We know the side opposite to 60 degree angle is 2, so x would be

$\frac{2}{\sqrt{3}}$

However, we can't have an irrational number in the demoninator so we multiply the fractice by root 3 over root 3:

$\frac{2}{\sqrt{3}} * \frac{\sqrt{3}}{\sqrt{3}}$

which gives us $\frac{2}{3} \sqrt{3}$

Find the length of side x in simplest radical form with a rational denominator.
