Question

The x co-ordinate of the centroid of a triangle whose vertices are (-3,-6), (-4,-2) and (-5, 0) is.

a) 4
b) -9.
c) -4.
d) 0​

Answer 1

We know that the coordinates of the centroid of a triangle whose angular points are(x1,y1),(x2,y2),(x3,y3)are

(3x1+x2+x3,3y1+y2+y3)

So, the coordinates of the centroid of a triangle whose vertices are  (0, 6), (8, 12) and (8, 0) are

(30+8+8,36+12+0)or,(316,6

Answer 2

Step-by-step explanation:

We know that the coordinates of the centroid of a triangle whose angular points are(x1,y1),(x2,y2),(x3,y3)are

• (3x1+x2+x3,3y1+y2+y3)

So, the coordinates of the centroid of a triangle whose vertices are  (0, 6), (8, 12) and (8, 0) are

• (30+8+8,36+12+0)or,(316,6
