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

step-by-step explanation:
a triangle's full angle is 180 degrees so 180 - 156 = 24. 24/2=12
Answer from: Quest
on monday rodney ate 1/4th of the sandwich = 3/12
on tuesday he ate 1/3rd of the sandwich = 4/12
therefore in total he has eaten = 3/12 + 4/12 = 7/12
thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
