The new roof will have the same size horizontal wood beams running across the house. However, the height of the roof will be 9 feet instead of 5 feet. Please help me find the length of the diagonal wood beams.

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.

x=-2

step-by-step explanation:

28-32x=92

-32x=92-28

-32x=64

x=64/-32

x=-2
