Answer:
ce=7 units
Step-by-step explanation:
In this problem
e is the midpoint of ab
so
ab=ae+eb and ae=eb
ab=2ae ------> equation A
c is the midpoint of ae
so
ae=ac+ce and ac=ce
ae=2ce -----> equation B
substitute equation B in equation A
ab=2(2ce)
ab=4ce
we have
ab=28 units
substitute
28=4ce
solve for ce
divide by 4 both sides
28/4=ce
Rewrite
ce=7 units
