Question

What is the measure of the "Central Angle" for the 20% section?

Answer 1

The sum of all central angle is 360.

Determine 20% of 360 to obtain central angle for 20% section.

`\begin{gathered} (20)/(100)*360^(\circ)=36^(\circ)\cdot2 \\ =72^(\circ) \end{gathered}`

So answer is 72 degrees.
