WebHow to solve for an angle using law of sines ... Law of Sines. The law states that, for every triangle, ... a proportion. Decide mathematic tasks. To solve a math equation, you need to decide what operation to perform on each side of the equation. Better than just an app. Better than just an app, ... 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
