Q3) The triangle ABC in a room as in the following sketch, which has the equation 6x + 8y + 3z = 15.. Find the coordinates of the points A, B and C, if F is the origin point in three-coordinate system .
System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
