Question

If A(4, – 3), B(3, – 2) and C(2, 8) are vertices of a triangle, then the distance of it's centroid from the y-axis is

Answer 1

$Let \: A(4,-3) = (x_{1} , y_{1}) , \\ B(3,-2) = (x_{2} , y_{2}) , \: C(2,8) = (x_{3} , y_{3}) \\ are \: Vertices \\of \: \triangle ABC$

$Centroid (G) = \Big( \frac{x_{1}+x_{2}+x_{3}}{3}, \frac{y_{1}+y_{2}+y_{3}}{3}\Big)$

$= \Big( \frac{4+3+2}{3} , \frac{-3-2+8}{3}\Big) \\= \Big( \frac{9}{3} , \frac{3}{3}\Big) \\= ( 3 , 1 )$

$Now, Distance \:of \: Centroid \:from \:the \\y-axis = x - coordinate \:of \: G \\= 3$

Therefore.,

$\red {Distance \:of \: Centroid \:from \:the }$

$\red {y-axis} \green { = 3 }$

Answer 2

Step-by-step explanation:

just apply formula of centroid and

we know that centroid from y axis = x coordinate of G
