Question

sabendo wue A (x,y)B (-1,8) e C (3,-10) sao vertices de um triangulo cujo baricentro e o ponto G (3,-2). Determine as coordenardas do vertice A.

Answer 1

$\frac{x-1+3}{3} =3=\ \textgreater \ x+2=9=\ \textgreater \ x=7 \\ \\ \frac{y+8-10}{3} =-2=\ \textgreater \ y-2=-6=\ \textgreater \ y=-4 \\ \\ A(7,-4)$
