Flashcard 10 - 11th Grade Mathematics: Geometry Flashcard Set for the SBAC


The correct answer is:

150 degrees


A dodecagon has \(12\) equal sides and angles.

The sum of the angles is \((12-2) \cdot 180 = 1800\) degrees.

Since each angle has an equal measure, each angle measures:

\[\dfrac{1800}{12} = 150\; \text{degrees}\]
