One way:
\(\frac{12}{30} x 360\)  (360 degrees in a circle which is what a pie chart is)
or \(\frac{2}{5}\) x 360
which is \(\frac{2}{5}x \frac{360}{1}\) = 144⁰ angle

Answer:

The angle you would use for blue on a pie chart is 144°.

Step-by-step explanation:

Consider the provided information.

The full chart would have 360 Degrees. That means 30 people equals to 360°

\(30\ people=360\)

Divide both sides by 30.

\(1\ people=12\)

Now multiply both sides by 12.

\(1\times 12\ people=12\times 12\)

\(12\ people=144\)

Hence, the angle you would use for blue on a pie chart is 144°.
