Following the sign conventions, si, r and li are negative. Law of sines1 on om c : lo sin ( ) Oc = so cv where cv = cm = r. thus. Also using sin ( ) = sin lo sin so |r| sin i. Similarly, law of sines on im c gives. |si| |r| sin t ni sin i = nt sin t (1) (2) (3) Combining (1), (2) and (3) ni sin (so |r|) lo. 1for a given abc, sin a a sin b sin c b c. , where a, b, c are lengths of the sides of the triangle and a, b, c are opposite angles respectively.
