Question

if the centroid of a triangle is at (-2,1) and two of its vertices are (1,-6)and (15,2)then find the third vertex of a triangle​

Answer 1

it would be (-xandy)

did not calculated

Answer 2

Answer:

Step-by-step explanation:

Let the third vertex be (X,y).

Now formula of centroid is:

1+15+X/3 , -6+2+y/3

=16+X/3 , -4+y/3

Now given centroid= -2,1

So,16+X/3=-2. And -4+y/3=1

X=-21. And. Y=7
