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

A non-right-angled triangle has vertices \(V\), \(W\) and \(X\)

Side \(v\) is opposite angle \(V\) and is unknown. Side \(w\) is opposite angle \(W\) and is 10 m. Side \(x\) is opposite angle \(X\) and is 12 m

Sides \(w\) and \(x\) meet at vertex \(V\). The included angle between them is \(V=51^{\circ}\). Find side \(v\)
