Answer with English please and what are degrees there

Degrees ($^\circ$) are a unit of measurement for angles. A full circle is divided into 360 degrees. When creating a pie chart, like the one partially shown in your image, the entire circle represents $100\%$ of the data. Each segment of the pie chart corresponds to a certain percentage of the total, and this percentage is converted into an angle measured in degrees.

For example, if a category represents $1/3$ of the total, its segment in the pie chart would have an angle of $1/3 \times 360^\circ = 120^\circ$. The numbers you see are the angular sizes of these segments.
