Answer:

DJ = 24

Explanation:

We are told from the question that J is the centroid of CDE, this means that J is the midpoint of DH, CJ and FE

If J is the centroid of DH, then 2DJ = JH

Also DJ + JH = DH

The equation becomes:

DJ + 2DJ = DH

3DJ= DH

Given

DH = 72

Hence 3DJ = 72

DJ = 72/3

DJ = 24

Hence the measure of DJ is 24
