then the value of the angle A, is

If in a triangle ABC, 2 (cos A)/(a) +(cos B)/(b)+2(cos C)/c=(a)/(bc)+b/(ca) then the value of the angle A is

If in a DeltaABC, 2(cosA)/(a)+(cosB)/(b)+(2cosC)/(c)=(a)/(bc)+(b)/(ca) Then, the value of the angleA is ...... Degree

In triangle ABC, 2(bc cosA-ac cosB-ab cosC)=

In triangleABC, 2(bc cosA+ac cosB+ab cosC)=

In a triangle ABC If (2cos A)/(a)+(cos B)/(b)+(2cos C)/(c)=(a)/(bc)+(b)/(ca) find the angle A .

If in a triangle ABC,(2cos A)/(a)+(cos B)/(b)+(2cos C)/(b)=(a)/(bc)+(b)/(ca), then prove that the triangle is right angled.

In Delta ABC If: 2(cosA)/a + (cos B)/(b) + 2(cosC)/(c) = a/(bc) + b/(ca) , then: /_A =

If in a triangle ABC, (cosA)/a=(cosB)/b=(cosC)/c ,then the triangle is

In DeltaABC,(cosA)/(a)+(cosB)/(b)+(cosC)/(c) =
