Star Stack (Posted on 2004-04-12) Difficulty: 3 of 5
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?

Note that you have a query:

.....I am looking for insight on this. ....

Solve for x,

(cosx)^3 + (cosx)^2 = 1/8.

I doubt that you'd get an answer from within the forum of this problem.  I think that a posting to one of the Forums, not sure which, would be the way to go.
