Quinton usually walks 28 yards south on pine street and 45 yard east on maple avenue to get to school. How much shorter would his walk be if he to the shortcut shown below

the answer is 11.2 (i know i’m late)

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.
