Accuracy 3. Using the image given. If a
M_ABD = 3x – 12° and mZCBD = 2x + 2°,
write an equation that would represent the
relationship between the two angles. Afterwards,
solve and find the unknown variable “x” and find
the measurements of ZABD and ZCBD.

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.
