1.) the diagonal of a rectangle is 25 meters long and makes an angle of 36 degree with one side of the rectangle. Find the area and the perimeter of the rectangle. 2.) A side of a square is 16 inches. The midpoints of its sides are joined to form an inscribed square. Another is drawn in such a way that its vertices would lie also at the midpoints of the sides of the second square. This process is continued infinitely. Find the sum of the areas of these infinite squares. 3.) A rectangle and a

Geometry (Greek γεωμετρία; geo = earth‚ metria = measure)‚ Its beginnings can be traced in ancient Egypt or early or before 1700 B.C. Due to necessity‚ every time the Nile River inundated and deposited fertile soil along the bank‚ the early Egyptian had to solve the problem of size and boundaries of land along the Nile River. Changes happened in the contour of the land had caused confusion among landowners. So a system of making boundaries‚ measuring lengths and areas had to be discovered

Geometry is considered one of the most elementary sciences known to man. It is the branch of mathematics concerned with the properties and relations of points‚ lines‚ surfaces‚ solids‚ and higher dimensional analogs. Geometry is used everywhere around us‚ even in places many people would not suspect it to be used. For example‚ geometry is used in football when constructors want to build a football stadium; it is used when creating the football‚ as well as‚ when a coach is drawing out plays on

have conducted my research through interview with someone familiar with construction and development as how geometry is used in these fields. The first step to development is to survey the property in order to document and draw the bounds and land surface shapes. The property will be represented by various geometry elements such as points‚ lines‚ arcs‚ circles‚ and other defined geometry shapes. Surveyors use scope on tripods witch use projection of line Referenced point on a stick in order to

Critique of Ian Bremmer’s ‘State Capitalism Comes of Age’‚ 88(3)‚ in Foreign Affairs‚ 88(3)‚ MayJune 2009. The assignment I am working on for Contemporary Research in Management module is very interesting. It is a critique‚ so something different than normal essey or report. A critique is a paper that gives a critical assessment of a book or article. Critique does not have to be negative‚ it could be possitive. I will treat this assignment as a check on my overall knowledge explored by the

NTRODUCTION: Geometry is used to know about all kinds of shapes and their properties in our daily life problems. Plane geometry - It is about all kinds of two dimensional shapes such as lines‚ circles and triangles. Solid geometry - It is about all kinds of three dimensional shapes like polygons‚ prisms‚ pyramids‚ sphere‚ cylinder. The word Geometry comes from Greek which means earth and metron. Geometry used in variousobjects such as surveying‚ astronomy‚ navigation and building

Ian Mc Ewan – Atonement Late phase of post modernism. From the fifties onwards‚ there is a rise of post modernism. In coincides with many aspects of western society (emancipation‚ Vietnam war…) Ground breaking philosophical essay – Jacques Derrida : introduced deep instruction and really attacked the very foundations of western humanism and cultures. In 1966‚ he wrote a theoretical paper – there is always an origin‚ a place of departure‚ an essence‚ a core reality‚ central of western culture
