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 Conversion of Sum Loo The Conversion of Sum Loo The Conversion of Sum Loo is a short story by Willa Cather. It was first published in "Library" in August 1900. After his first wife dies without giving him the progeny his recently deceased father strongly wished him to have, Sum Chin, who grew up in China and now lives in San Francisco, decides to get married to the daughter of a friend he had in China.
