Carbon-14 is an element that loses about 10% of its mass every millennium (I. e. 1000 years). A sample of
Carbon-14 has 600 grams.
Write a function that gives the sample's mass in grams. S(t). millennia from today.
S(t) =

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
