Moe Mentum owns a goat that will eat anything, especially the tennis balls that are hit into Moe's Yard from a neighboring tennis court. To keep his goat from eating more tennis balls, Moe decides to tether it in a corner of his yard at Point A, as shown in the figure. The tether is 20 feet long.
What is the probability that a tennis ball hit into Moe's yard
will be within reach of the tethered goat?

there is no graph so i cant sorry

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.
