Asection of a broadwalk is made using 15 boards. each board is 9 1/4 inches wide. the total width of the section is 144 inches. the 14 spacings between the boards are equal. what is the width, in inches, of the spacing between each board? write as a fraction in simplest form.

hiking down a winding trail.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
