Use the sine rule in a non-right-angled triangle

Triangle \(MNP\) is non-right-angled

Side \(m\) is opposite angle \(M\), side \(n\) is opposite angle \(N\), and side \(p\) is opposite angle \(P\)

Angles \(M\) and \(N\) are \(69^{\circ}\) and \(68^{\circ}\), respectively. Angle \(P\) is the third angle of the triangle

Side \(n\) is 59 cm. Side \(m\) is unknown and must be found; side \(p\) is not required

The known side-angle pair is side \(n\) opposite angle \(N\)
