It states the ratio of the length …
WebThe Law of Sines relates the sides & angles of a triangle, using the sine function. If the triangle’s sides are a, b, & c, across from angles A, B, & C, then the Law of Sines tells us that a/sin (A) = b/sin (B) = c/sin (C). We can use this equation to solve for an unknown side or angle in a triangle. WebThe sine law can also be used for a right triangle. sine law can be used in oblique(non-right) as well as in a right triangle to establish a relationship between the ratios of sides and their respective opposite angles. ...
WebIn trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles. According to the law, where a, b, and c are the lengths of the sides of a triangle, and α, β, and γ are the opposite angles (see figure 2), while R is the radius of the triangle ...
