Q8 of 53 Page 115

In ΔABC, G (-4, -7) is the centroid. If A (-14, -19) and B(3, 5) then find theco-ordinates of C.


The coordinates of the centroid (x,y) od a triangle formed by points (a,b), (c,d), (e,f) is given by



In the given question (x,y) = (-4,-7)


Hence


Solving for e, we get


e = -1



Solving for f, we get


f = -7


Hence the coordinates of the third point are (-1,-7)
