Odgovor:

Centroid # = (20)/3, (16)/3#

Pojasnilo:

Vogali trikotnika so

# (3,2) = barva (modra) (x_1, y_1 #

# (5,5) = barva (modra) (x_2, y_2 #

# (12,9) = barva (modra) (x_3, y_3 #

Centroid najdemo s pomočjo formule

centroid # = (x_1 + x_2 + x_3) / 3, (y_1 + y_2 + y_3) / 3 #

# = (3+5+12)/3, (2+5+9)/3#

# = (20)/3, (16)/3#
