1 ponto

( )C(1,2)

( )C(2,-2)

( )C(5,2)

( )C(1,-6)

( )C(-2,6)

​

Answer 1

$\sf{xb=(x1+x2+x3)/3}$

• $\sf{=(-1+5+2)/3}$

• $\sf{=(-1+7)/3}$

• $\sf{=6/3}$

• $\sf{=+2}$

$\sf{yb=(y1+y2+y3)/3}$

• $\sf{=(3-7-2)/3}$

• $\sf{=(-4-2)/3}$

• $\sf{=-6/3}$

• $\sf{=-2}$

$\red{\boxed{\boxed{baricentro=( 2 , -2)}}}$
