Webb2 jan. 2024 · There are six different scenarios related to the ambiguous case of the Law of sines: three result in one triangle, one results in two triangles and two result in no triangle. We'll look at three examples: one for one triangle, one for two triangles and one for no triangles. Example 4.2.1. Solve the triangle if: ∠A = 112 ∘, a = 45, b = 24. WebbLet us assume that we want to find the angle A. For this, we need to know the length of the opposite side ‘a’, and another angle-side pair such as angle B and the side b, or angle C and the side c. The calculations follow the side-side-angle (SSA) theorem. The Law of Sines is used for the calculations of the other unknowns.
