Best ResponseYou've already chosen the best response.0x^2 + y^2 = r^2 Dx 2x + Dy 2y = Dr 2r ; dicide the 2s Dx x + Dy y = Dr r Dr = Dx x + Dy y //r Dx =35; Dy =25. lets find x, y and r :)

Best ResponseYou've already chosen the best response.0Dr = 35(100) + 25(190)  sqrt(10000 + 190^2)............you might to close your eyes for this then :)

Best ResponseYou've already chosen the best response.0the 100 came from multipying the 25 by 100 right

Best ResponseYou've already chosen the best response.0150 + 4(35) = 150 + 140 = ...290.....

Best ResponseYou've already chosen the best response.0Dr = 35(290) + 25(100)  looks better to me eh sqrt(10000 + 290^2)

Best ResponseYou've already chosen the best response.0..... well the Dr part is correct, double check the distances to be sure.

Best ResponseYou've already chosen the best response.0for last step i did it differently, i did (140+100)/290 *(35+25)

Best ResponseYou've already chosen the best response.0Dr = De e + Dn n //r De = 35; Dn = 25 e = 150 + 4(35); n = 4(25) e = 290; n = 100 Dr = 35(290) + 25(100) //r r = sqrt(290^2 + 100^2) = sqrt(84100 + 10000) = sqrt(94100) Dr = 10150 + 2500 12650  =  sqrt(94100) sqrt(94100) Dr = 41.2378
