To solve this problem, we can use the Law of Sines or the Law of Cosines. Given that we know two sides of the triangle (LM = 13.2 cm and MN = 7.3 cm) and the included angle (angle $L = 32.5^\circ$), we can use the Law of Sines to find the possible value for angle $N$.

The Law of Sines states: $\frac{\sin L}{LM} = \frac{\sin N}{MN}$ Where:

• $L$ is the angle at vertex $L$,
• $N$ is the angle at vertex $N$,
• $LM$ and $MN$ are the lengths of the sides opposite these angles.

Step 1: Apply the Law of Sines

Substitute the known values into the equation: $\frac{\sin 32.5^\circ}{13.2} = \frac{\sin N}{7.3}$

Step 2: Solve for $\sin N$

Rearranging the equation: $\sin N = \frac{7.3 \times \sin 32.5^\circ}{13.2}$ Now calculate: $\sin 32.5^\circ \approx 0.532$ So, $\sin N = \frac{7.3 \times 0.532}{13.2} \approx \frac{3.8856}{13.2} \approx 0.294$

Step 3: Solve for angle $N$

Now, take the inverse sine (or arcsin) to find angle $N$: $N = \sin^{-1}(0.294)$

Calculating: $N \approx 17.1^\circ$

Thus, a possible value for angle $N$ is approximately 17.1°.

Summary

Angle $N \approx 17.1^\circ$, based on the Law of Sines.
