Write 3 a rotios of 3:7

6:14; 9:21; 12:28

Step-by-step explanation:

3 x 2 = 6 and 7 x 2 = 14

3 x 3 = 9 and 7 x 3 = 21

3 x 4 = 12 and 7 x 4 = 28

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
