A 30-60-90 triangle always has side ratios of 1: `sqrt(3):2`

Which means if the side opposite the 30 degree angle is 2, the side opposite the 60 degree angle will be `sqrt(3)`

times larger than the side opp. the 30 degree angle.  So its length would be 2`sqrt(3)`

The side opposite the 90 angle is always twice as large as the side oppostite the 30 degree angle.  Therefore the side would have a length of 4.
