Adam, Brad, Casey, and Dylan are on one side of a river and Emily is alone on the opposite side. The children want to find the distance across the river between Adam and Emily. The following
measurements have already been found. (The distance from Adam-Brad -75 ft. Adam-Casey -
25 ft. Adam-Dylan -90 ft. Brad-Casey-80 ft. Brad-Dylan - 22 ft.) The line extending from Emily
to Adam to Casey is straight and so is the line between Emily, Brad, and Dylan. What is the
distance between Emily and Adam?

step-by-step explanation:

80

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
