Answer:

∠B < ∠A < ∠C

Explanation:

Given,

In triangle ABC,


AB=x^2+(x)/(2)


BC=x^2+(x)/(3)


CA=x^2-(x)/(2)

At x = 6,


AB=6^2+(6)/(2)=36 + 3 = 39


BC=6^2+(6)/(3)=36 + 2 = 38


CA=6^2-(6)/(2)=36 - 3 = 33

We know that in a triangle, the interior angle opposite to largest side is largest, opposite to smallest side is smallest and opposite to medium side is medium.

Here, CA < BC < AB

Also, angles A, B and C are opposite angles of the sides BC, CA and AB respectively,

Hence, ∠B < ∠A < ∠C

Which is the required order of angles.

The size of the angle is always corresponding to the opposite side to it, for example
∠A corresponds to side BC
∠C corresponds to side AB
∠B corresponds to side AC
thus given x=6 then:
AC=x^2-x/2=33
AB=x^2+x/2=39
BC=x^2+x/3=34
thus the order of angles from the smallest to the largest is ∠B, ∠A, ∠C
