Answer:
[tex]25\le AC\le 121[/tex]
Step-by-step explanation:
The key to this question is that the length of a side of a triangle is larger than the difference of the other 2 sides and is smaller than the sum of the other 2 sides. Hence the length of AC is larger than (or equal to, in case A, C, D do not form a triangle but are on the same line) [tex]73-48=25[/tex] and is smaller than (or equal to) [tex]73+48=121[/tex].
