How do I find the shorter leg on a 30-60-90 triangle?

Question

the shorter leg is opposite the smallest angle (30°)

You need to knowe at least ONE side length to be able to work out the other lenghts

If you could draw this triangle, it would be better.
If you can't, take that rule:
The largest leg (side) opposes the largest angle in the triangle. This is a concept.

So now can you find the largest leg??
