In a `Delta ABC` if A=(1,2) and the internal angle bisectors through B and C are y=x and y=-2x. The inradius r of `Delta ABC` is (A) `1/sqrt3` (B) `1/sqrt2` (C) `2/3` (D) none of these

In a triangle ABC, if A-=(1,2) and the internal angle bisectors through B and C are y=x and y=-2x, then the inradius r of DeltaABC is

In a triangle ABC.if A(1,2) and the internal angle bisetors through B and C are y=x and y=-2x, then the in radius r of Delta ABC is :

In a triangle ABC if 2a= sqrt(3)b+c then

Given b=2 , c= sqrt(3), angle A= 30^@ then inradius of Delta ABC is :-

In Delta ABC , if a=sqrt3+1,b=2,B=45^@ , then A=

In a Delta ABC if b=a(sqrt(3)-1) and /_C=30^(@) then the measure of the angle A is

The equation of the base of an equilateral triangle ABC is x+y=2 and the vertex is (2,-1). The area of the triangle ABC is: (sqrt(2))/(6) (b) (sqrt(3))/(6) (c) (sqrt(3))/(8) (d) None of these

In A Delta ABC if ( sqrt(3)-1)a=2b, A=3B then c is

ABC be a triangle with A(1,3),y=x,y=-2x are the equations of internal angular bisectors of /_B and /_C and area of triangle ABC is k units,then 2k is
