The Sine Rule is a mathematical formula used in trigonometry to find unknown lengths or angles in non-right-angled triangles. It states that the ratio of the length of a side of a triangle to the sine of its opposite angle is constant for all three sides and angles. This can be expressed as \fraca\sin A = \fracb\sin B = \fracc\sin C, where a, b, and c are the sides, and A, B, and C are the corresponding opposite angles. The Sine Rule is particularly useful in solving problems involving triangles when only some sides or angles are known. It can help determine missing information in various fields, including engineering, architecture, and navigation. By applying the Sine Rule, one can easily calculate distances and angles, making it a valuable tool in both theoretical
