According to the United States Geological Survey, there is over 1,383 billion cubic kilometers (km3of water on the planet. A km3is the volume of a cube measuring 1 kilometer on each side. If 97/100 of the water is found in the ocean, how much water, in km3is found in our oceans?

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

is only a line? i think so

sweetheart, there isn't a cube below.
