Friday Funny: What is the Angle for X?


David Meego - Click for blog homepageHere is another mathematical puzzle for you.

This was recently asked in a Year 12 Further Maths exam in Victoria, Australia.

It was a multiple choice question, so I thought I would have a poll to see how well you can answer the question.

The question is:

A 50 cent coin has 12 sides of equal length. Two 50 cent coins are balanced next to each other on a table so they meet along one edge.

What is the Angle for X?
