In4ABC, AB = AC. Bis (3; 6) and Cis (7; 12). Gis thecentroid of4ABC. G moves on a line x-y= 1. Find coordinatesofG

Dear ajinkya

G lies on x-y=1

let co ordinate of G is (h,h-1)

since AB =Ac

co distance og G from B and C will be same

BG = CG

(h-3)² +(h-1-6)² = (h-7)² + (h-1-12)²

h=8

so G (8,7)
