One way:
[tex] \frac{12}{30} x 360 [/tex]  (360 degrees in a circle which is what a pie chart is)
or [tex] \frac{2}{5} [/tex] x 360
which is [tex] \frac{2}{5}x \frac{360}{1} [/tex] = 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°

[tex]30\ people=360[/tex]

Divide both sides by 30.

[tex]1\ people=12[/tex]

Now multiply both sides by 12.

[tex]1\times 12\ people=12\times 12[/tex]

[tex]12\ people=144[/tex]

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