For 30 60 90 triangles, the ratio of the side lengths is
where the first is the shorter leg, the second is the longer leg, and the third is the hypotenuse (the longest side that doesn't form a 90 degree angle)
so the ratio of the longer leg to the hypotenuse is <span>
or
</span>
<span>which equals </span>
