Question

determine as coordenadas do baricentro de um triângulo, cujos vértices são:
A (1,-3) B (-4,7) C (-6,8)

Answer 1

A(1,-3)
B(-4,7)
C(-6,8)

xg = ( xa + xb + xc ) / 3

xg = ( 1 - 4 - 6 ) / 3 = -9/3 = -3

yg = ( ya + yb + yc ) / 3

yg = ( -3 + 7 + 8 ) / 3 = 12/3 = 4

G(-3,4)

Answer 2

Boa noite Kary

Gx = (Ax + Bx + Cx)/3
Gx = (1 - 4 - 6)/3 = -9/3 = -3

Gy = (Ay + By + Cy)/3
Gy = (-3 + 7 + 8)/3 = 12/3 = 4


G(-3, 4)
