Question

Dê as coordenadas do baricentro de um triângulo cujos vértices são A(1, -2), B(2,-4) e C(3,-3)

Answer 1

Resposta:

$bx = \frac{xa + xb + xc}{3} \\ bx = \frac{1 + 2 + 3}{ 3} \\ bx = \frac{6}{3} \\ bx = 2 \\ \\ by = \frac{ya + yb + yc}{3} \\ by = \frac{ - 2 - 4 - 3}{3} \\ by = \frac{ - 9}{3} \\ by = - 3 \\ \\ par \: ordenado \: (2 \: e \: - 3)$
