Question

if two vertices of a triangle are (2,5) and (5,4) its centroid be(4,2) then the third vertex is .​

Answer 1

Answer:

(5,-3)

Step-by-step explanation:

Let the third vertex be ( x , y )

Then

Centroid = ( 4,2)

So according to the question

4= 2+5+ x / 3

12= 7 + x

x = 5

Now !

2= 5+ 4 + y / 3

6 = 9 + y

y= -3

So the vertex are ( 5, -3)
