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

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

(i) Find the length of Angle Bisector

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

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

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

If x,y,z be the lengths of the internal bisectors of the angles of a triangle 1,m,n be the lengths of these bisectors produced to meet the circumcircle,then show that x^(-1)cos((A)/(2))+y^(-1)cos((B)/(2))+z^(-1)cos((C)/(2))=a^(-1)+b^(-1)+c^(-1)

If x,y,z be the lengths of the internal bisectors of the angles of a triangle 1,m, n be the lengths of these bisectors produced to meet the circumcircle,then show that l cos((A)/(2))+m cos((B)/(2))+n cos((C)/(2))=a+b+c
