By using the properties of definite integrals, evaluate the integrals`int_0^pi (xdx)/(1+sinx)`

Explanation

To evaluate the integral \( I = \int_0^\pi \frac{x}{1 + \sin x} \, dx \) using the properties of definite integrals, we can follow these steps:

### Step 1: Define the Integral
Let
\[ I = \int_0^\pi \frac{x}{1 + \sin x} \, dx \]
