In `DeltaABC`, a =125, b=62 and c=123, find the value of sinB.

Explanation

To find the value of \( \sin B \) in triangle \( ABC \) with sides \( a = 125 \), \( b = 62 \), and \( c = 123 \), we can use the following steps:

### Step 1: Calculate the semi-perimeter \( s \)
The semi-perimeter \( s \) of triangle \( ABC \) is given by the formula:
\[ s = \frac{a + b + c}{2} \]
Substituting the values:
