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. (See diagram.)

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?

(In reply to Parallel intercepts, mainly - a different approach by brianjn)

From a viewing of my prior remarks under IE, not sure about Netcape:

The sqrt sign appeared as an 'i' followed by a careted 'i'.

The degree circle has been as a quote followed by two lines that form the '3rd' quadrant; I am assuming that readers of this understand those concepts, otherwise I extend my apologies.
