Since lines AB and CD are parallel, we can apply the properties of angles formed by a transversal cutting through parallel lines.
Given that \( N = 51^\circ \), we can identify the relationship between angle \( N \) and angle \( P \) based on their positions. If angle \( P \) is corresponding, alternate interior, or supplementary with angle \( N \), we can find its measure accordingly.
1. **If \( P \) is corresponding to \( N \)**: Then \( P \) would also equal \( 51^\circ \).
2. **If \( P \) is an alternate interior angle**: Then \( P \) would also equal \( 51^\circ \).
3. **If \( P \) is supplementary to \( N \)**: Then \( P + N = 180^\circ \). Here, \( P = 180^\circ - 51^\circ = 129^\circ \).
Since the problem does not specify the positions of angles \( N \) and \( P \), we need to evaluate the possible choices based on typical scenarios. The options given are 51°, 174°, 39°, and 129°.
If we consider \( P \) as either corresponding to or an alternate interior angle of \( N \) as stated above, the best matches would be:
- 51° (if they are corresponding or alternate).
- 129° (if they are supplementary).
Based on the information typically relating to parallel lines and angles, if \( P \) were to be found on the same transversal as \( N \) but on the opposite side (making them supplementary), the correct answer would be \( 129^\circ\).
Thus, the measure of \( P \) is:
