Finding angles of obtuse triangles
WebFirst, if you know two angles and the side opposite one of them, then you can determine the side opposite the other one of them. For instance, if angle A = 30°, angle B = 45°, and side a = 16, then the law of sines says (sin 30°)/16 = (sin 45°)/b. Solving for bgives b = 16(sin 45°)/(sin 30°) = 22.6274.
