A combination lock has three dials, each of which can be set to A, B, C, D, or E. How many different possible combinations does this lock have?

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

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.
