Solution:

AB = AC - BC
AB = 65 - 40
AB = 25

Proof:  

a)  Line postulate, where each point in a number line corresponds to a distinct letter (paraphrased). 

The letters that corresponds to the points are arranged alphabetically.

b)  Addition Postulate, where AB + BC = AC
                                               AC - AB = BC
                                               AC - BC = AB
