How to solve two triangles with law of sin
WebThe Law of Sines can be used to solve oblique triangles, which are non-right triangles. According to the Law of Sines, the ratio of the measurement of one of the angles to the length of its opposite side equals the other two ratios of angle measure to opposite side. There are three possible cases: ASA, AAS, SSA. WebLet’s now look at a couple of examples of these two situations and how the Law of Sines is used to solve the triangles. Example 1: Solve the given triangle using the Law of Sines. Round lengths to the nearest tenth . and angle measurements to the nearest degree. A = 70°, B = 55°, and a = 12
