sin theta= opposite/adjacent....can i use this formula for triangles other than right triangles?

You can't use the formula you described (which is incorrect, btw, sine(theta) = opposite/hypotenuse), but you can use the Law of Sines (see the source link for information).

Your formula is mixed up. In any right triangle, sin theta = opposite/hypotenuse
It is tan theta that is opposite/adjacent
All identities are true only for right triangles.

i dont know what you mean by theta, but usually the formula in a right triangle is: sin alpha=opposite/hypotenuse and not adjacent
