Best Answer

It is 9.1 inches (approx).

L*[sin(x) + sin(2x) + sin(3x) +sin(4x)] = 28 inches where x = 360/10 = 36 degrees.

Since x = 36 deg,

sin(x) = sin(4x) and sin(2x) = sin(3x)

So

L*[2sin(x) + 2sin(2x)] = 28 inches

L*[sin(x) + sin(2x)] = 14 inches

L* 1.539 = 14 approx so that L = 9.098 inches or 9.1 inches, approx.

How long is each side of a 17.25 inch octagon?

There is insufficient information to answer the question. There is no indication that the octagon is regular and therefore, you may not assume that it is. Even it you were told that it is a regular octagon, there is still insufficient information: the answer will depend on what the 17.25 inch is a measure of - the diagonal of the octagon or its height (width).
