Thread: Geometry Sin Problem

There is a picture of the problem i created in the paint program. Or, if you don't like links or whatever, the picture is below.
Find Sin A.

Thank you for your time.

Here is the image.

From what I remember Sin is Opposite/hypotenuse (Soh-Cah-Toa)

So, Sin A would be 2 root 3 divided by 4. In exact terms, that is .866
