Equilateral pentagon of δ can be seen from the figure: Simplifying, δ is obtained as function of α and β: The remaining angles of the pentagon can be found geometrically: The remaining angles of the orange and blue triangles are readily found by noting that two angles of an isosceles triangle are equal while all three angles sum to 180°. Then formula_7 and the two remaining angles of the green triangle can be found from four equations stating that the sum of the angles of the pentagon is 540°, the sum of the angles of the green triangle is 180°, the angle
The Sum of Our Discontent The Sum of Our Discontent The Sum of Our Discontent is a nonfiction book by David Boyle. It was published by Texere in 2001. The tagline and theme of the book is "Why numbers make us irrational".
