 ## Sine Rule – Ambiguous Case – Example

ExampleBy taking into consideration the ambiguous case. Solve ∆ABC such that c = 6cm, a = 5cm and ∠A = 40°Answer:Step 1: To prove whether this is an ambiguous case/non-ambiguous case[begin{gathered}sin {40^o} = frac{y}{6} hfill \y = 6sin {40^o} hfill \y = 3.857cm hfill \end{gathered} ]y < a < cTherefore, this is an ambiguous case. … Read moreSine Rule – Ambiguous Case – Example
