Tangent WebThe law of sines can be used when two angles and a side of a triangle are known. Consider the following problem, in which we have two angles and the side opposite one of them: A = 35 o, B = 49 o, and a = 7. The first part we calculate is the third angle, C. C = 180 o-35 o-49 o = 96 o. Then, using the Law of Sines, b and c can be calculated black and gold woman wall art
