The angles of `triangle ABC` are in A.P. and `b:c= sqrt(3):sqrt(2)` find `angle A , angle B , angle C`.

Explanation

To solve the problem, we need to find the angles of triangle ABC, given that the angles are in Arithmetic Progression (A.P.) and the ratio of sides \( b:c = \sqrt{3}:\sqrt{2} \).

### Step-by-Step Solution:

1. **Define the Angles in A.P.**:
Let the angles of triangle ABC be \( A \), \( B \), and \( C \). Since they are in A.P., we can express them as:
\[
A = a - d, \quad B = a, \quad C = a + d
