To find the sine of angle \( C \) in triangle \( ABC \) given the side lengths, we can use the sine function's definition in the context of a triangle:
\[
\sin(C) = \frac{\text{opposite}}{\text{hypotenuse}}
\]
In this triangle, based on the description, we will need to identify which sides correspond to angle \( C \).
1. **Side lengths:**
- \( AB = 97 \) (the top side)
- \( AC = 72 \) (the left slanting side)
- \( BC = 65 \) (the right slanting side)
2. **Identifying the sides related to angle \( C \):**
- Opposite side to angle \( C \) (which would be side \( AB \)), and the hypotenuse in this case can be taken as \( AC \) or \( BC \) depending on how angle \( C \) is viewed.
By convention (in right triangles), we generally consider the hypotenuse to be the longest side, and we can find the sine using each side effectively.
To find \( \sin C \):
\[
\sin(C) = \frac{\text{length of the side opposite angle } C}{\text{length of the hypotenuse}}
\]
Here, we can re-evaluate with respect to triangle properties or even use the Law of Cosines to find angle \( C \) first, then compute \(\sin C\).
Using the Law of Cosines to find angle \( C \):
\[
c^2 = a^2 + b^2 - 2ab \cdot \cos(C)
\]
Substituting \( AB = c = 97 \), \( AC = b = 72 \), and \( BC = a = 65 \):
\[
97^2 = 72^2 + 65^2 - 2 \cdot 72 \cdot 65 \cdot \cos(C)
\]
Calculating these:
1. \( 97^2 = 9409 \)
2. \( 72^2 = 5184 \)
3. \( 65^2 = 4225 \)
Now, put these into the Law of Cosines formula:
\[
9409 = 5184 + 4225 - 2 \cdot 72 \cdot 65 \cdot \cos(C)
\]
\[
9409 = 9409 - 2 \cdot 72 \cdot 65 \cos(C)
\]
From here, we isolate \( \cos(C) \):
\[
0 = -2 \cdot 72 \cdot 65 \cdot \cos(C)
\]
Since the equation doesn't require solving \( C \) as it yields no practical solution unless specified otherwise or if any angle measure was missed or incorrectly used.
For \( \sin C \), we can further calculate or find out that:
From triangle inequality or via trigonometric identities or further methods could yield exactly \( 0 \) or the paper trail leads elsewhere confirming boundaries.
### Ultimately
Upon using exact sine values:
\[
\sin C \text{ yields its challenge unless corroborated)},
\]
Lastly:
Given specifics above, note out each triangle defines \( \sin C \) itself might yield ambiguity without defined reference.
The correct angle \( C \) can give \( \sin C \) as:
\[
\sin(C) tightly rounds around descriptive but resolving \( \frac{opposite/hypotenuse} \) implies it leads to specified measurable units matched in proper fractions, refined would yield \( \frac{65}{97} \to .\( = \approx 0.669, \) precise as quality aimed toward \( . \)
\]
If locating solutions, consider revisiting geometry constraints or matching baseline radius ensures suitability in unique triangles.
**Final surrogate arrangement may finalize `\sin C = \frac{opposite}{hypotenuse}` implicating tactical resolution thus concluding.**
Going beyond or revisiting lines bases, yields could thus have 00 as practical endpoint envisioned.

\sin(C) = \frac{\text{opposite}}{\text{hypotenuse}}
