Web17 jun. 2024 · Step 1: First, let’s identify what type of information our triangle is providing us with. Notice that we are given angle A , angle B, and side b for AAS. Since our triangle contains AAS, we know we can apply the law of sine to find the missing side. Step 2: Next, let’s write our law of sine formula and then plug in our given information. Web13 dec. 2024 · The Sine Rule, also known as the law of sines, is exceptionally helpful when it comes to investigating the properties of a triangle. While the three trigonometric ratios, sine, cosine and tangent, can help you a lot with right angled triangles, the Sine Rule will even work for scalene triangles.
