If cos B=(sin A)/(2sin C) then prove that the triangle is isosceles.

If 2 cos A = (sin B)/(sin C) then show that the triangle is isosceles.

In a o+ABC, if cos C=(sin A)/(2sin B), prove that the triangle is isosceles.

In a triangle ABC, if cos A=(sin B)/(2sin C), show that the triangle is isosceles.

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

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

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

In a Delta ABC, if cos C = (sin A)/(2 sin B) , show that the triangle is isosceles.

In any triangle ABC, if (cos A + 2 cos C)/(cos A + 2 cos B) = (sin B)/(sin C) then prove that, the triangle is either isosceles or right angled.
