Question

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

Answer 1

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

Answer 2

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??

Answer 3

I know the longer leg is 9, and that's all I know.
