In the corporate sector, what should be the approximate number of degrees in the central angle?

From the given pie chart, the percentage distribution for the Corporate Sector is $34\%$.
The total angle of a circle is $360^{\circ }$, which corresponds to $100\%$.
To find the central angle corresponding to $34\%$:

$$\text{Central Angle}=\frac{34}{100}\times 360^{\circ }$$

$$\text{Central Angle}=\frac{34\times 36}{10}=\frac{1224}{10}=122.4^{\circ }$$

The approximate number of degrees is $122$.
