8. In the diagram, AEB is straight and angles A and B are right. Calculate the total distance DE+EC 15 10 9. (Continuation) If AE 20 and EB 10 instead, would DE+EC be the same? A 10 E 20 B 10. (Continuation) You have seen that the value chosen for AE determines the value of DE+ EC. One also says that DE+EC is a function of AE. Letting r stand for AE (and 30-x for EB), write a formula for this function. Graph this formula using a graphing tool. Locate the point on the graph that represents the shortest path from D to C through E Draw an accurate picture of this path, and make a conjecture about angles AED and BEC Consider the slopes or use a protractor to test your conjecture.
