Solution:
Given a table of data;
Where the total hours in 50 hours
The hours spent for jogging is 20 hours.
The sum of angles about a point or in a circle is, 360°
The portion for jogging in degrees is
[tex]=\frac{hours\text{ of jogging}}{total\text{ hours}}\times360\degree[/tex]
Substitute into the formula above
[tex]\begin{gathered} =\frac{20}{50}\times360\degree \\ =\frac{2}{5}\times360\degree \\ =144\degree \end{gathered}[/tex]
Hence, the portion for jogging is 144°
