What is the slope of a roof that rises 12 feet over a run of 28 feet?

A StartFraction negative 3 Over 7 EndFraction

C StartFraction 3 Over 7 EndFraction

B StartFraction negative 7 Over 3 EndFraction

D StartFraction 7 Over 3 EndFraction

slope = rise/run = 12/28  = 3/7

hence slope is 3/7 feet or 0.43 feet.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

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.
