Question

centroid of (1,2)(-1,-2)(3,-3) verticies is ​

Answer 1

Step-by-step explanation:

$Centroid = ( \frac{ x_1+x_2+x_3}{3},\frac{ y_1+y_2+y_3}{3}) \\ = (\frac{1 - + ( - 1) + 3}{3}, \: \frac{2 + ( - 2) + ( - 3)}{3} ) \\ = (\frac{1 - 1 + 3}{3}, \: \frac{2 - 2 - 3}{3} ) \\ = ( \frac{3}{3} , \: \frac{ - 3}{3}) \\ = (1 , \: - 1) \\ thus \: the \: coordinates \: of \: centroid \: \\ are \: (1 , \: - 1).$
