If in a triangle ABC,(a+b+c)(b+c-a)=k.bc, then :k 6c.0 4

In A B C ,(a+b+c)(b+c-a)=k b c if k 0 = 4

In A B C ,(a+b+c)(b+c-a)=k b c if k 0 = 4

In A B C ,(a+b+c)(b+c-a)=k b c if k 0 = 4

The centroid of the triangle formed by (a ,b),(b,c),(c,a) is the origin and a^(3)+b^(3)+c^(3)=k(abc) ,then the value of "k" is

If A+B=C,|A|=2|B|and B.C=0, then

If A+B=C,|A|=2|B|and B.C=0, then

In any triangle ABC,sum a sin(B-C) in equal to ab+bc+ca b.0 c.3abc d.3(a+b+c)
