Question

find the centroid of the triangle whose verticals are ( 7, 2) (5, 1) and (3, 4)​

Answer 1

Centroid =(7+5+3)/3=5
And (2+1+4)/3=7/3

Answer 2

Answer:

Step-by-step explanation:

a (x , y ) =  [ x1 + x2 + x3 , y1 + y2 + y3 ]

                           3                   3

Here :  x1 = 7 , x2 = 5 , x3 = 3 , y1 = 2 , y2 = 1 , y3 = 4

substitute these values in  the formula

a (x , y ) = [ 7 + 5 + 3 ] , [ 2 + 1 + 4 ]

                      3                  3

a (x , y ) = [ 15/3 ] , [ 7/3 ]

a (x , y ) = [ 5 , 7/3 ]

SO THE CENTROID WITH VERTICES ( 7, 2) ,  (5, 1) AND (3, 4)​ IS [ 5 , 7/3 ]
