Answer:
The answer to your question is: BD = 7.5
Step-by-step explanation:
Data
C is the midppoint of AD
B is the midpoint of AC
AC = 5
BD = ?
Process
We know that B is the mid point of AC, then AB = BC
AB + BC = 5
but 2AB = 5
AB = 5/2
AB = 2.5 = BC
Then AC = CD if AC = 5 then CD = 5
Finally
BD = BC + CD
BD = 2.5 + 5
BD = 7.5
