Harold created a figure for a puzzle board. He used a copy machine to make an image of the figure 70% larger than the original. Carmen then used Harold's enlarged image and reduced it 50% in size to make Carmen's image of the figure. Finally, Emma reduced Carmen's image 20% to make Emma's image of the figure. What percent of the original figure size is Emma's image

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
