`A+B+C =0^@=>sin A+ sin B +sin C =`

Let cos A + cos B + cos C = 0 and sin A + sin B + sin C = 0 then which of the following statement(s) is/are correct?

A + B + C = 0 ^ (@) rArr sin A + sin B + sin C =

If A+B+C=0^@ " then " sin A + sin B + sin C =

A + B + C = 0 ^ (0) rArr sin A + sin B + sin C =

If A + B + C = 180^(@) , prove that sin(B + C - A) + sin (C + A - B) + sin(A + B + C) = 4 sin A sin B sin C.

If A+B+C= pi and (sin 2 A + sin 2B + sin 2 C)/(sin A + sin B + sin C ) = lamda sin ((A)/(2)) sin ((B)/(2)) sin ((C )/(2)) , then the value of lamda must be

If A+B+C=0^(@) then sin A +sin B+sin C=

In a triangle ABC . If cos Acos B + sin A sin B sin C = 1 , then sin A + sin B+ sin C =

If A+B+C=0^(@) then sin A+sin B+sin C=
