Three pentagram-shaped stars (the stars formed from the diagonals of a regular pentagon) are stacked up so that the bottom two ends of the tips touch the middle ends of the tips of the star below.
The distance from the top of the stack to the floor (where the bottom star's "feet" rest) is 4 feet.
What is the distance between the bottom two ends of the tips of the stack that touch the floor?
Charlie and K Sengupta have one answer.
Larry, nikki, vectorboy and myself have a different value.
We find that Charlie is seldom in error, but he has acknowledged that he is not infallible.
Gamer, you don't have a solution posted for this. Either one of these is clearly correct. Please declare your hand.
