1. **State the problem:**
We have triangle $\triangle HIJ$ with side $h = 97$ cm opposite angle $H$, angle $H = 144^\circ$, and angle $I = 24^\circ$. We need to find the length of side $i$ opposite angle $I$.
2. **Find the missing angle:**
The sum of angles in a triangle is $180^\circ$.
$$J = 180^\circ - H - I = 180^\circ - 144^\circ - 24^\circ = 12^\circ$$
3. **Use the Law of Sines:**
The Law of Sines states:
$$\frac{h}{\sin H} = \frac{i}{\sin I} = \frac{j}{\sin J}$$
We want to find $i$, so:
$$i = h \times \frac{\sin I}{\sin H}$$
4. **Calculate the sines:**
$$\sin 144^\circ = \sin(180^\circ - 36^\circ) = \sin 36^\circ \approx 0.5878$$
$$\sin 24^\circ \approx 0.4067$$
5. **Substitute values and calculate $i$:**
$$i = 97 \times \frac{0.4067}{0.5878}$$
Show intermediate cancellation:
$$i = 97 \times \cancel{\frac{0.4067}{0.5878}}$$
Calculate the fraction:
$$\frac{0.4067}{0.5878} \approx 0.6921$$
So:
$$i \approx 97 \times 0.6921 = 67.13$$
6. **Round to the nearest tenth:**
$$i \approx 67.1 \text{ cm}$$
**Final answer:** The length of side $i$ is approximately $67.1$ cm.
