Answer 1

Step-by-step explanation:

Coordinates of the centroid of triangle ABC = (4,0)

Step-by-step explanation:

Coordinates of vertice A = (-1,0)

Coordinates of vertice B = (5,-2)

Coordinates of vertice C = (8,2)

To find Coordinates of the centroid :

\begin{gathered}(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})\\\\\implies (\frac{-1+5+8}{3},\frac{0+(-2)+2}{3})\\\\\implies (4,0)\end{gathered}(3x1+x2+x3,3y1+y2+y3)⟹(3−1+5+8,30+(−2)+2)⟹(4,0)

Hence, Coordinates of the centroid of triangle ABC = (4,0)

Answer 2

Answer:(-2,1)

Step-by-step explanation:

Just add x coordinate and divide by three similar for y
