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
