Question 3
Two fifty-cent coins are placed next to each other on a table top, forming an angle $\theta$ as shown in the figure below. Each coin takes the shape of a dodecagon with 12 sides of equal length. Find the value of $\theta$ in degrees.
Source note: the intended answer additionally uses regular dodecagons; equal side lengths alone do not specify all angles.
