Recall that $$\sin = {\text{opposite} \over \text{hypotenuse}}$$

Because we applying sin to A, we have $$CB \over AB$$.

Can you take it from here?

Also, that isn't a triangle, because $$9^2 + 6^2 ≠ 15^2$$. The rule for the triangle side length does not hold true here either, because $$9+6$$ is not greater than 15.
