Question

the centriod of triangle whose vertices
are (-76) (2,-2) (8,5)​

Answer 1

Answer:

formula (X1+X2+X3 )/3,(y1+y2+y3)/3

Step-by-step explanation:

= -7+2+8/3, 6+(-2)+5/3

= 3/3, 9/3

=(1,3)

Answer 2

$\: \: \huge \underline{ \boxed{ \star\bf{answer}}}$

$\: \bullet \underline {\bf \: by \: using \: centroid \: formula}$

$\bf{x=\dfrac{x_1+x_2+x_3}{3} \: and \: y=\dfrac{y_1+y_2+y_3}{3}}$

$\: \implies \displaystyle\bf{x = \frac{ - 7 + 2 + 8}{3}}$

$\implies \displaystyle \bf{x = \frac{ - 5 + 8}{3} }$

$\: \implies \displaystyle \bf{x = \frac{3}{3} = 1}$

$\: \: \: \mapsto \displaystyle \bf{y = \frac{ 6 - 2 + 5}{3} }$

$\: \mapsto \displaystyle \bf{y = \frac{9}{3} = 3}$
