" In any "Delta ABC" if "2cos B=(a)/(c)" ,then the triangle is "

In Delta ABC if 2 cos B = ( a)/(c ) , then the triangle is

In Delta ABC, if 2 cos B=a//c , then the triangle is

In any triangle ABC if 2cos B=(a)/(c), then the triangle is(A) Right angled (C) Isosceles (B) Equilateral (D) None of these

In triangle ABC, If cos B= a/(2c) , then the triangle is-

In Delta ABC, if cos A+cos B+ cos C=3//2 , then the triangle is

If in Delta ABC, c(a+b) cos ""B/2=b (a+c) cos ""C/2, the triangle is

If in Delta ABC, c(a+b) cos ""B/2=b (a+c) cos ""C/2, the triangle is

In Delta ABC, if c(a+b) cos B//2=b (a+c) cos C//2 , then the triangle is

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