" If in a triangle "ABC,a^(2)Cos^(2)A=b^(2)+c^(2)," then "

In a triangle ABC,a^(2)cos^(2)A=b^(2)+c^(2) then triangle is

If in a triangle Delta ABC,a^(2)cos^(2)A-b^(2)-c^(2)=0 then

In a triangle ! ABC, a^2cos^2A=b^2+c^2 then

In a triangle ABC,cos^(2)A+cos^(2)B+cos^(2)C=

In a triangle ABC, a^2cos^2A=b^2+c^2 then triangle is

If in a triangle ABC, (bc)/(2 cos A) = b^(2) + c^(2) - 2bc cos A then prove that the triangle must be isosceles.

If in a triangle ABC, (bc)/(2 cos A) = b^(2) + c^(2) - 2bc cos A then prove that the triangle must be isosceless

If in a triangle ABC, (bc)/(2 cos A) = b^(2) + c^(2) - 2bc cos A then prove that the triangle must be isosceles.

If in a triangle ABC, (bc)/(2 cos A) = b^(2) + c^(2) - 2bc cos A then prove that the triangle must be isosceless
