ok it turns out that a 30-60-90 triangle is a special triangle where the side lengths form the ratio shown in this image here http://hotmath.com/hotmath_help/topics/30-60-90-triangles/triangle1.gif x is the short leg 2x is the hypotenuse (in other words, the hypotenuse is twice as long as the short leg) x*sqrt(3) is the long leg

jim_thompson5910 · Answer

notice how 8 is twice as big as 4
and how 8 is the hypotenuse while 4 is the short leg (short leg is opposite smallest angle)
