What is the measure of an angle whose degree is five times its compliment?

150 Degrees

Step-by-step explanation:

150 degrees

since the ratio is 5: 1, certainly there are 6 parts,

so, one part equals, 30, which 180/6,

hence the complement angle which is five times more will be 5*30 = 150.

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.
