all sin is sin97 degrees Fahrenheit = 36.1 degrees Celsius
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.
It is:- sin(40) = 0.6427876097
Sin(163 degrees) = 0.2924 approx.
Sin(80 degrees) = 0.9848, approx.
