In a 30-60-90 triangle, the length of the hypotenuse is 12. What is the length of the shortest side.

The ratio of a 30-60-90 triangle is 1:√3:2 meaning the longest side is √3 times the length of the shortest side and the hypotenuse is 2 times larger than the shortest side. meaning the shortest side is half the length of the hypotenuse so the shortest side is 12/2 meaning the shortest side is 6
