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. WebTo find an unknown side, we need to know the corresponding angle and a known ratio.
