Answer 1

Question-

The co-ordinates of a centroid of ∆ PQR, is G (6,9). Write possible values of P(x1, y1), Q(x2, y2), R(x3,y3).​

Answer-

• P(x1, y1) = (7,10)
• Q(x2,y2) = (5,10)
• R(x3,y3) =  (6,8)

Answer 2

GIVEN: The co-ordinates of a centroid of ∆ PQR, is G (6,9

To find: values of P(x1, y1), Q(x2, y2), R(x3,y3).​

Solution:

Centroid formula is,

X,Y= (a1,b1,c1.0), (a2,b2,c2)

X= a1+b1+c1/3= x1+x2+x3/3= 6

x1+x2+x3= 18

Ya2+b2+b3/3= y1+y2+y3/3= 9

y1+y2+y3=27

Possible values are,

x1+x2+x3= 18 and y1+y2+y3=27
