Question

dado o triangulo abc a (7, -2), b (4,6) e c (2,8) determine as cordenadas de seu baricentro g
(preciso urgente pra agr )

Answer 1

As coordenadas do baricentro serão:
$X_{g}=\frac{x_{A}+x_{B}+x_{C}}{3}=\frac{7+4+2}{3}=\frac{13}{3}$
$Y_{g}=\frac{y_{A}+y_{B}+y_{C}}{3}=\frac{-2+6+8}{3}=\frac{12}{3}=4$
Portanto:
$G:(X_{g};Y_{g})=(\frac{13}{3};4)$
