Question

7. By centroid formula,find X
Co-ordinate for given values
M(-6,-3),N(4,2),B(-7,1)​

Answer 1

Answer:

Let the given vertices of a triangle be

M(-6,-3), N(4,2), & B(-7,1)

$centeroid = ( \frac{ x_{1} + x_{2}+ x_{3} }{3} )( \frac{ y_{1} + y_{2} + y_{3} }{3} )$

$(\frac{ - 6 + 4 + ( - 7)}{3} )( \frac{ - 3 + 2 + 1}{3} )$

$( \frac{ - 6 + 4 - 7}{3} )( \frac{ - 3 + 3}{3} )$

$( \frac{ - 2 - 7}{3} )( \frac{0}{3})$

$( \frac{ -9}{3} )(0)$

$( - 3)(0)$

x = -3 , y = 0
