The coordinates of centroid are: (10/3, 3)
Step-by-step explanation:
The formula for calculating centroid of a triangle is:
Here (x1,y1) are the coordinates of first vertex
(x2,y2) are the coordinates of second vertex
(x3,y3) are the coordinates of third vertex
Given:
G(-2,5) = (x1,y1)
H(6,5) =(x2,y2)
J(6,-1) = (x3,y3)
Let I be the centroid of the triangle
Putting the values in the formula
The coordinates of centroid are: (10/3, 3)

Step-by-step explanation:
ΔSTR and ΔSQR are similar triangles
so TR/SR=SR/QR
--> q/14=4/q
--> q = 2
