WebAccording to the law of sines. a/Sin (A) = b/Sin (B) = c/Sin (C) One real-life application of the sine rule is the sine bar, which is used to measure the angle of tilt in engineering.. Other common examples include measuring distances in navigation and the measurement of the distance between two stars in astronomy. 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.
