C. 8.6 mm
D. 17.2 mm

Answer 1

Answer:A. 3 mm

B. 7 mm

C. 8.6 mm

D. 17.2 mm

Explanation:

Answer 2

Option D.
`KR=17.2\ mm`

Explanation:

we know that

The Centroid of a Triangle is the center of the triangle that can be calculated as the point of intersection of all the three medians of a triangle. The centroid divides each median in a ratio of
`2:1`

In this problem the point R represent the centroid of triangle JKL

therefore

`KR=(2/3)KM`

substitute the value

`KR=(2/3)(25.8)=17.2\ mm`
