In `Delta ABC, if a(b cos C+ c cos B)=2ka^2`, then k =

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

In Delta ABC , if cos A + 2 cos B + cos C = 2 then a,b,c = in

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

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

In Delta ABC, sum a^2 (cos^2 B-cos^2 C) =

In Delta ABC, if a cos^2""C/2+c cos^2""A/2=(3b)/2 then a,b,c are in

In any Delta ABC, prove that :a(b cos C-c cos B)=b^(2)-c^(2)

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

In Delta ABC , (a)/( cos A) = (b) /( cos B ) = ( c ) /( cos C ) , If b= 2 then the area of the triangle is
