Question

-) Find the co-ordinate of centroid of the triangles whose vertices are
(4,7), (8,4), (7, 11)​

Answer 1

Answer:

(19/3, 22/3)               Convert to mixed number

Step-by-step explanation:

let the vertices be A(4,7), B(8,4), and C(7, 11)​

A(x1,y1) B(x2,y2) C(x3,y3)

centroid G = ((x1+x2+x3)/3,  (y1,y2,y3)/3)

                  = ((4+8+7)/3, (7+4+11)/3)

                  = (19/3, 22/3)

                  .Convert to mixed number

Answer 2

Answer: x=19/3 y=22/3

Step-by-step explanation: A=(4,7), x1=4, y1=7

B=(8,4), x2=8, y2=4

C=(7,11), x3=7, y3=11

By Using Centroid firmula

X=x1 + x2 +x3/3 ; Y=y1 + y2 + y3/3

X=4 + 8 + 7 /3 ; Y=7 + 4 + 11 /3

X=19/3 ; Y=22/3
