<h3>What is a pie chart?</h3>A pie chart is a graphical representation of data in a circle. In this pie chart, the area or percentage of the whole circle is 100%
Thus, we can obtain the values of the different groups represented in the pie chart by systematically dividing the circle accordingly.
The rule to follow is that vertical angles are always congruent (equal) as they have two lines that intersect to form opposite angles.
<h3>Data and Calculations:</h3>Research, Sales, and Marketing = 50% of the budget (half of the pie chart)
Research = 18%
Sales and Marketing = 32% (50% - 18%)
Research equals Media and Support and Media and Support are equal.
Therefore, Media is 9% (18%/2) and Support is also 9%.
Since opposite angles are always equal, Engineering (opposite to Sales and Marketing combined) is 32%.
This results in a total of 100% (18% + 32% + 9% + 9% +32%)
