WebThe absolute value of a number may be thought of as its distance from zero along a number line; this interpretation is analogous to the distance function assigned to a real number in the real number system. For example, the absolute value of ?4 is 4, and the absolute value of 4 is 4, both without regard to sign. WebThe law of sines formula is used for any triangle apart from SAS triangle and SSS triangle. It says, a/sin A = b/sin B = c/sin C where, a, b, and c are the lengths of the triangle A, B, and C are the angles of the triangle. This formula can be represented in three different forms given as, a/sinA = b/sinB = c/sinC sinA/a = sinB/b = sinC/c
