Web26 mrt. 2016 · Use the law with c on the left-hand side of the equation to solve for the cosine of angle C. Use a calculator to find the measure of angle C. C = cos –1 (0.979) = 11.763° Angle C measures about 12 degrees, which means that angle B is 180 – (61 + 12) = 180 – 73 = 107 degrees. The ambiguous case causes a bit of confusion. WebUnfortunately, while the Law of Sines enables us to address many non-right triangle cases, it does not help us with triangles where the known angle is between two known sides, a SAS (side-angle-side) triangle, or when all three sides are known, but no angles are known, a SSS (side-side-side) triangle.In this section, we will investigate another tool for solving …
