Question

The vertices of a triangle are (4. y). (6, 9) and (x, 4). The coordinates
of its centroid are (3,6). The values of x and y are a​

Answer 1

Answer:

x' = 3, x1=4, x2= 6, x3=x

y' = 6, y1 = y, y2= 9, y3 =4

x' = (x1+x2+x3)/3

3= (4+6+x)/3

9 = 10+ x

x = 9-10

x = -1

y' = ( y1+y2+y3)/3

6 = ( y+9+4)/3

18 = y + 13

y = 18-3

y = 15
