"WebT HE LAW OF SINES allows us to solve triangles that are not right-angled, and are called oblique triangles. It states the following: The sides of a triangle are to one another in the same ratio as the sines of their opposite angles. a: b: c = sin A : sin B : sin C. Specifically, side a is to side b as the sine of angle A is to the sine of angle B. " - How to solve for an angle using law of sines

WebWhen you solve your equation using arcsin, you're getting the acute angle at vertex C 1, the one labeled as θ in the diagram. The relationship between θ and the angle at vertex C is θ + C = 180. The reason: triangle A C C 1 is isosceles so ∠ A C C 1 = ∠ C C 1 A = θ. Therefore θ and C are supplementary angles. WebCalculate sides and angles for triangles using law of sines step-by-step.
