@nid - show how did u use the distance formula?

-----
BC = k-6)i + 15j

sqrt((k-6)^2 + 15^2) = 25

therefore

(k-6)2 = 252 - 152 = 400

k-6= sqrt(400) = 20

hence, k = 26

@shrey - read it again

@nid

check the quoted one!!!

i said 26!!~~

Hehe, yes... It was cleared long ago...

Welcome  :)


Before you close this forever, just something I wanna add.

x : x - 3,  the colon is just a way of expressing mathematical information. It can be read as: x is such that...
