Question about Jr. Varsity contest problem.
by Daniel Xu - Wednesday, October 10, 2018, 7:42 PM
 

The October 2018 Junior Varsity Problem 6 asks: 

A convex polygon with nn sides has interior angles of

30,60,90,,n30.30∘,60∘,90∘,…,n⋅30∘.
What is the sum of all possible nn?


It says that the answer is 11, for n=3 and n=8. However, with n=8, the largest angle is 240˚, which clearly makes the polygon concave, instead of convex! Shouldn't the answer just be 3? I'm so confuzzled here.

Thanks for the reply Daniel.

I'll double check the wording of everything tomorrow, but I think you and another poster both noticed this important point.

We'll make sure everything (including any updates to the leaders), get's taken care of right away tomorrow morning.

I'll reply the same here as in the other thread.

I double checked the wording this morning and we have updated the problem to have $3$ as the correct answer. The winners list has been updated to reflect this change. (This update did not remove any winners, only added some winners.)

Thank you for your feedback and we hope to see you again for the November competition!
