The ambiguous case of the sine rule

Question 1 of 8

Calculator allowed

Consider the proposed non-right-angled triangle \(VWX\)

Side \(v\) is opposite angle \(V\) and has length 160 cm. Side \(x\) is opposite angle \(X\) and has length 187 cm. Side \(w\), opposite angle \(W\), is not given

The angle at vertex \(V\) is \(V=58^{\circ}\). At \(V\), sides \(w\) and \(x\) meet, so \(V\) is not the angle between the two given sides \(v\) and \(x\). Angles \(W\) and \(X\) are unknown

This information fits two possible triangles, one with an acute angle \(X\) and one with an obtuse angle \(X\)

2 marks

Use the sine rule to determine both values of angle \(X\) to 2 decimal places
