Question

Two vertices of a triangle are (1,3) and
(3.1). If the coordinates of the centroid
of the triangle is (2,1), find the
coordinates of the third vertex of the
triangle.​

Answer 1

Answer:

(2,-1)

Step-by-step explanation:

Let third vertex =(x, y)

Centroid =(2, 1)

1+3+x÷3=2

X=2

3+1+y÷3=1

Y=-1

Third vertex =(2, - 1)
