suppose J is betwwen H and K. Use the segment addition Postulate to sove for X. Then find the length of each segment.

HJ=3(x+2)
JK= 3x-4
KH= 44

The Segment Addition Postulate is:

If B is between A and C, then AB + BC = AC.

So in your case HJ + JK = KH
6x + 2 = 44
6x = 42
x =7
HJ = 27
JK = 44-27 = 17
