Circles with radii 3, 4, 5 touch each other externally. If P is the point of intersection of tangents to these circle at their points of contact, find the distance of P from the points of contact.

But still I am one.
I cannot do everything,
But still I can do something;
And because I cannot do everything
I will not refuse to do the something that I can do.

use radical axis funda...u will get d answer.....:-
let the centre of these circles be
(h1,k1) , (h2,k2) , (h3,k3)
form eqns...e.g :-
(x-h1)^2 + (y-k1)^2 = 9 etc..
find radical axis of any two pairs......
find their pt. of intersectiion...& staisfy it in the 3rd radical axis...
u will get some relation.....then its easy...aplly distance fromulae..........:))
