To use the Law of Sines to find the length of side \( c \), we need more information about the triangle. Specifically, we would need either the angle \( B \) or the angle \( C \) or the length of side \( b \).

The Law of Sines states:

\[
\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}
\]

Given:
- \( \angle A = 72^\circ \)
- \( a = 1246 \, \text{mm} \)

To solve for \( c \), we need either \( \angle B \) or \( \angle C \).

However, since we don't have enough information to calculate the exact length of side \( c \), please provide the measure of either \( \angle B \) or \( \angle C \) or the length of side \( b \) so that we can proceed with the calculation.
