Answer:

DC = 14

CM = 7

Step-by-step explanation:

Here, given the centroid, we want to calculate DC and CM

An important property of the centroid point is that it divides the median in the ratio 2 to 1

so DC being the longer will take the ratio of 2 while CM will take 1

Let’s work with the ratio

DC = 2/3 * 21 = 14

CM = 1/3 * 21 = 7
