Answer:

3

Step-by-step explanation:

Points C, D, and E are collinear.

Segment CD = 8

Segment CE = 11

Segment DE = ?

According to the segment addition postulate:

[tex] CD + DE = CE [/tex]

[tex] 8 + DE = 11 [/tex] (substitution)

Subtract 8 from both sides

[tex] 8 + DE - 8 = 11 - 8 [/tex]

[tex] DE = 3 [/tex]

The missing lenght indicated = 3
