Question

O Baricentro do triângulo de vértices A( 3,2 ), B ( 7,7 ) e C ( 5,-3 ) é:
A) G(0,0)
B) G(5,2)
C) G(3,-2)
D) G(5,0)
E) G(2,-3)

Answer 1

Resposta:

Explicação passo-a-passo:

xG = (xA + xB + xC)/3

xG = ( 3 + 7 + 5 )/3

xG = 15/3

xG = 5

yG = (yA + yB + yC)/3

yG = (2 + 7 - 3)/3

yG = 6/3

yG = 2

G(5, 2)

Letra B
