Question

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

Answer 1

Answer:

(-1, -7)

Step-by-step explanation:

Three vertice A, B and C(x, y) will form a centroid G(-4, -7).

According to the centroid formula:

$(\dfrac{-14+3+x}{3},\dfrac{-19+5+y}{3} )=(-4, -7)$

The solutions of Point C are $(x,y)=(-1, -7)$.
