Announcement Regarding Division M Question 7:

Question 7 on the DIvision M Monthly Contest involved a diagram (not drawn to scale) in the shape of a star that included a pentagon in the middle:

The problem stated that $\mathrm{\angle }CAD={20}^{\circ }$ AND that all the outside triangles $\mathrm{△}AFJ$, $\mathrm{△}BGF$, etc, were all isosceles.

This, however, is impossible, as it both implies that pentagon $FGHIJ$ has interior angles of ${100}^{\circ }$ and that it is equiangular (so would have angles of ${108}^{\circ }$).

For scoring of the competition, the problem has been removed. The updated problem will state that only $\mathrm{△}AFJ$, $\mathrm{△}BGF$, and $\mathrm{△}CHG$ are isosceles (with $\mathrm{\angle }CAD$ still ${20}^{\circ }$).
