Step 1

1 of 3First find the angle $\alpha$ using the Law of Sines:

$\begin{aligned} \dfrac{\sin\alpha}{22.3}&=\dfrac{\sin100^\circ}{16.1}\\ \sin\alpha&=\dfrac{22.3\cdot\sin100^\circ}{16.1}\\ \sin\alpha&\approx1.36 \end{aligned}$

Since the value of $\sin$ is less than $1$, we cannot find the angle $\alpha$. In that case, the triangle does not exist.
