If b=3,c=2,`angle A=120^(0)` then length of the bisector of A is

If b=3,c=2,A=120^(@) then length of the bisector of A is "

(i) Find the length of Angle Bisector

In triangle ABC, angle C = 120^(@). If h be the harmonic mean of the lengths of the sides BC and CA, then the length of the bisector of angle BCA is

A(1,-1,-3),B(2,1,-2)&C(-5,2,-6) are the position vectors of the vertices of a triangle ABC.The length of the bisector of its internal angle at A is :

In a /_ABC,/_C=120^(@) If he be the harmonic mean of the length of the sides BC and CA,then the length of the bisector of /_BCA is

If A(3,1,-1),B(4,-1,1),C(5,2,1) be the vertices of a Delta ABC then the length of the internal bisector of angle A is
