?

anonymous · Answer

$$\sin30=12/x$$
$$x=12/\sin30$$
$$x=24$$

sin30=1/2
12divided by 1/2=24

24 because the short side must be half of the hypotenuse.  no trig needed

anonymous · Answer

double the triangle and you will have an equilateral triangle with all sides 12 (equilateral because all degrees are 60) 
so it is obvious that the short side is half of the hypotenuse
