In a `Delta ABC`, 2 sinA cos B + 2 sin B cos C + 2 sin cos A = sin A + sin B + sin C, then `Delta ABC`is

In a Delta ABC , 2 sinA cos B + 2 sin B cos C + 2 sin C cos A = sin A + sin B + sin C, then Delta ABC is (a) Isoceles (b) Right Angled (c) Acute (d) None of these

If cos A = (sin B)/(2 sin C) , then Delta ABC is

IF cos A=(sin B)/(2 sin C) , then Delta ABC is

If : 2 sin B cdot cos C = sin A, then Delta ABC is

In Delta ABC, cscA (sin B cos C + cos 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 =

In Delta ABC, if cos A cos B+ sin A sin B sin C=1 , then a:b:c =

In Delta ABC, (cos A)/(c sin B)+(cos B)/( a sin C)+(cos C)/( b sin A) =

In Delta ABC , (sin A(a- b cos C))/( sin C ( c-b cos A)) =
