[" n "/_ABC,a,b,c" are sides and "A,B,C" are angles of triangle.The correct relation is "CE2005" (Sc) "],[[" A) "(b-c)sin((B-C)/(2))=a cos(A)/(2)," (B) "(b-c)cos(A)/(2)=asin((B-C)/(2))],[" C) "(b-c)sin((B+C)/(2))=acos(A)/(2)," (D) "(b-c)cos(A)/(2)=2a sin((B+C)/(2))]]

In triangle ABC,a,b,c are the lengths of its sides and A,B,C are the angles of triangle ABC .The correct relation is given by (a) (b-c)sin((B-C)/(2))=a(cos A)/(2) (b) (b-c)cos((A)/(2))=as in(B-C)/(2)(c)(b+c)sin((B+C)/(2))=a(cos A)/(2)(d)(b-c)cos((A)/(2))=2a(sin(B+C))/(2)

In triangle ABC, a, b, c are the lengths of its sides and A, B C are the angles of triangle ABC. The correct relation is

If a,b,c are sides of Delta ABC are in A.P.then

A, B and C are interior angles of a triangle ABC, then sin ((B + C)/(2)) =
