Question

the centroid of triangle with vertices (1,-2),(x,3),(5,y) is origin then find the value ofx and y​

Answer 1

x1+x2+x3/3
1+x+5 /3=0
6+x/3=0
6+x=0 (3 goes on your that side)
x=-6


y1+y2+y3/3
-2+3+y/3=0
+1+y/3=0
1+y=0 same as x
y=-1

Answer 2

Heya

______________________________

Centroid of a Trangle having vertices

a , b , c And d , e , f is

h =( a + b + c )/2

k = ( d + e + f )/2

ACCORDING TO THE QUESTION

0 = { 1 + x + 5 } /3

{ 1 + x + 5 } = 0

x = -6

And.

0 = { -2 + 3 + y }/2

{ y +1 } = 0

y = -1

So, x = -6 And y = -1
