Answer:
Step-by-step explanation:
Just for completeness you could represent the longest line as c and the inequality would be
a<b<c
Rule: The largest angle is opposite the largest side. The smallest angle is opposite the smallest side.
<ACB is opposite the longest line (c). So one of B or C is correct.
<CAB is the next largest angle. It is opposite b
<CBA must be the smallest angle.
So the correct order must be <CBA, <CAB, <ACB must be the order you seek.
