Question

in triangle abc m is the mid point of bc , length of am is 9 n is the point on am such that mn=1. what is the distance of n fron the centroid of the triahgle

Answer 1

Answer:

not too hard...,....,..

Step-by-step explanation:

nothing's

Answer 2

Answer:

Correct option is A)

M is the mid point of BC.

⇒AM is the median of ΔABC,

G is the centroid of ΔABC.

⇒G divides AM in the ratio 2:1

⇒AG:GM=2:1

Given, AM=9

Let AG=x

Then GM=(9−x)

x:(9−x)=2:1

⇒

9−x

x

=

1

2

⇒x=2(9−x)

⇒x=18−2x

⇒3x=18

⇒x=6

∴GM=9−6=3

Now, GN=GM−NM=3−1=2
