Determine triangle angles knowing sides
WebExample 2. This is also an SSS triangle. In this triangle we know the three sides x = 5.1, y = 7.9 and z = 3.5. Use The Law of Cosines to find angle X first: cos (X) = (y 2 + z 2 − x 2 )/2yz. cos (X) = ( (7.9) 2 + (3.5) 2 − (5.1) 2 … WebSep 1, 2024 · The 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.
