Yes, thanks guys :))

What rubbish, this is not your answer.

Shreyas1,

I think that you have copied this and your other answers off another site.

I have seen no evidence that you even know how to do your own Latex.

I would not be surprised if you do not even know what LaTex is.

Idk either 

I found that the centre of the circle is    \((a,\frac{9a-16}{3})\)      where a is int the set ot reals

and the radius sqared iis                   \(r^2= 10a^2-40a+\frac{370}{9}\)

so the equation of the circle is

\((x-a)^2+(y-\frac{9a-16}{3})^2= 10a^2-40a+\frac{370}{9}\)

I know that is right becasue I have graphed it but when i take it further I get in a mess.  :/

Why would we hurry when you cannot even be bothered presenting your problem properly?

Why do you think it is 36?

Hi shteyas1,

I would have used a few more words like

And why exactly are those two triangles similar ?

BUT your logic is good.

LOL
