... In the previous section, we learned about a special relationship that exists between the sides of a right angle triangle. This relationship is called the Pythagorean theorem, and it is described by the equation a 2 + b 2 = c 2 . In this section, we will investigate if a relationship exists between t ...

... A utility worker is installing a 25 ft telephone pole. The work order indicates that two guy wires (a wire running from the ground to the top of the pole) should be placed opposite each other and at a 65° angle of elevation to the pole. To the nearest tenth of a foot, how far apart are the guy wire ...
