The sine rule(also known as the "law of sines") is:

a/sin A = b/sin B = c/sin C

where the uppercase letters represent angles of a triangle and the lowercase letters represent the sides opposite the angles (side "a" is opposite angle "A", and so on.)

Sine Ratio(for angles of right triangles):

Sine of an angle = side opposite the angle/hypotenuse

written as

sin=opp/hyp.
