In `DeltaABC`, if `(sin A)/(c sin B) + (sin B)/(c) + (sin C)/(b) = (c)/(ab) + (b)/(ac) + (a)/(bc)`, then the value of angle A is

In DeltaABC,(sin 2A+ sin 2B+ sin 2C)/(sin A + sin B+ sin C)=

In any DeltaABC , sin A + sin B + sin C =

In any DeltaABC , sin A + sin B + sin C =

In DeltaABC , if sin A sin B =(ab)/(c^(2)) , then the triangle is

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

In any DeltaABC , prove that (sin B)/(sin C) = (c-a cos B)/(b-a cos C)
