The Cartesian plane consists of two perpendicular lines called x-axis and y-axis which, together with the intersection point (the origin), define a two-dimensional coordinate system that makes it possible to specify the location of points in the plane. Following this same line of reasoning, to describe the location of a point in space we need to introduce a third dimension into the two-dimensional system. For this, from the Cartesian plane, we define a z axis (perpendicular to both axes) passing through the origin which, together with the x axis and y axis will constitute our three-dimensional coordinate system.
Accordingly we can say that two perpendicular lines can represent a three-dimensional coordinate system.
It's important because it is easy to apply it too tightly and impede circulation. Allows for smoother fit and prevents gaping caused by variation in contour of the limb.
The emissions of carbon dioxide would reduce because then they will consume less gasoline. Instead of coal burning, this would reduce the overall concentrations of greenhouse gas emissions and generate energy from wind.
