Question

as coordenadas do baricentro G(GX , YG) do triângulo de vértices A(1,2), B(0,0) e C(2,13) é. a) (4,5) b) (1,5) c) (2,4) d) (1,6)​

Answer 1

$G (1 ; 5)$

Alternativa B.

Para determinar as coordenadas do baricentro temos:

$GX = (1 + 0 + 2) / 3\\\\GX = 3 / 3\\\\GX = 1$

$GY = (2 + 0 + 13) / 3\\\\GY = 15 / 3\\\\GY = 5$

$G (1 ; 5)$
