If a,b and c also represent the sides of a triangle , and a,b,c are in g.p then the complete set of `alpha^2 = (r^2 +r +1)/(r^2-r+1)`is

If a,b and c are the sides of Delta ABC for which r_1=8,r_2=12 and r_3=24 then the ordered triad (a,b,c)=

The exradii of a triangle r_(1),r_(2),r_(3) are in HP , then the sides a,b,c are

If the sides of triangle ABC are in G.P with common ratio r (r<1) , show that r<1/2(sqrt5+1)

If three successive terms of as G.P. with commonratio rgt1 form the sides of a triangle and [r] denotes the integral part of x the [r]+[-r]= (A) 0 (B) 1 (C) -1 (D) none of these

If three successive terms of as G.P. with commonratio rgt1 form the sides of a triangle and [r] denotes the integral part of x the [r]+[-r]= (A) 0 (B) 1 (C) -1 (D) none of these

If three successive terms of as G.P. with commonratio rgt1 form the sides of a triangle and [r] denotes the integral part of x the [r]+[-r]= (A) 0 (B) 1 (C) -1 (D) none of these
