Question

Find Co- ordinates of centroid of ∆ ABC , if A ( 11,-4) , B ( 4,3 ) , C ( 3-5) .​

Answer 1

Answer:

(6,-2)

Step-by-step explanation:

centroid of a triangle(x,y)=(X1+X2+X3/3,Y1+Y2+Y3/3)

=[11+4+3/3,-4+3+(-5)/3]

=(18/3,-6/3)

=(6,-2)

Answer 2

Answer:

Use the formula (x1+x2+x3)/3 ,( y1+y2+y3)/3

Step-by-step explanation:

x1=11 x2=4 x3=3

x-coordinate= (11+4+3)/3=18/3=6

y-coordinate = (-4+3+ -5)/3=-6/3=-2
