Question

In the figure triangle, find the coordinates of A.A(x,y)B(3,-5)
C(-7,4)andG(2,-1)​

Answer 1

Answer:

g is a centroid of triangle abc

g (a1+a2+a3/3,b1+b2+b3/3)

g(x+3+(-7))/3,y+(-5)+4/3)

g (x-4/3,y-1/3)......1

It is being given g (2,-1).......2

from (1)and (2)

x-4/3=2,y-1/3=-1

x-4=6,y-1=-3

x=10,y=-2

hence, coordinates of A are (10,-2)
