Given: 1 is complementary to 2. 2 is complementary to 3. prove: m1 = m3 what is the missing statement in step 3 of the proof? m1 = m2 m1 + m2 = 90° m2 = m3 m2 + m3 = 180°

First, it has to be noted that the term complementary refers to two angles with measures summing up to 90o.  A two-column proof is shown below.

                                    M1 = m2                                 conclusion

                                    M1 + m2 = 90o                                           Definition of complementary angles

The missing term here is:

                                    M2 + m3 = 90o              Definition of complementary angles

                                    M1 + m2 = m2 + m3             

Subtracting m2 from both sides of the equation,

                                    M1 = m3

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

i think the answer would be c
