1.	The chord of contact of tangents drawn from any point on the circle x2+y2=a2 to the circle x2+y2=b2 touches x2+y2=c2, where a,b,c>0, then a,b,c are in
Answer» The chord of contact of tangents drawn from any point on the circle $x^{2} + y^{2} = a^{2}$ to the circle $x^{2} + y^{2} = b^{2}$ touches $x^{2} + y^{2} = c^{2}$ , where $a, b, c > 0,$ then $a, b, c$ are in
