Question

two vertices of ABC are a(-1,4)and b(5,2) and it's centroid is g(0,-3 the coordinate of c is​

Answer 1

Step-by-step explanation:

Let the coordinates of c be (x,y)

We know,

Centroid =( ( x1+x2+x3 )/3 , (y1+y2+y3)/3)

Therefore

((-1+5+x)/3 , (4+2+y)/3)=(0,-3)

Therefore

(-1+5+x)/3=0 ...........(i)

And

(4+2+y)/3= -3.............(ii)

Now solve this two equations and you will get the value of x and y..
