In the first round of a card game niki scored 20 points then she lost 10 points on one turn and an addiotal 25 points on her final turn

That's 35 points because one you take ten away from 20 you get 10 then you add 25 and that's how i got 35

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

x/3-10=8

x/3=18

x=48
