(See attached file for full problem description with diagrams) --- Geometry has many practical applications in everyday life. Estimating heights of objects, finding distances, and calculating areas and volumes are commonplace. One of the most fundamental theorems in geometry, the Pythagorean Theorem, allows us to make many of these calculations. The Pythagorean Theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides, as shown in the diagram below. The problems in this Unit will give you an opportunity to practice these applications. Solve the following problems and submit them in a Word document. 1. A Little Le... click for more
