N△jkl, kn=21 m. what is the length of kx?

KX = 2/3(21)

KX = 14 m

Step-by-step explanation:

To solve this problem, we need to use the theorem about the intersection of all three medians, which states

"The medians of a triangle concurrent at a point that is two-thirds from each vertex to the mid point at the opposite side".

If we apply this theorem, we have

So, if

Then,

Therefore,
