Answer:
28.8 and 180
Step-by-step explanation:
you just times B by 2/5 to get C and divide it by 2/5 to get A
C = (72)(2/5) = 28.8 km³
A = (72)/(2/5) = 180 km³
We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.
The answer you are looking for would be X=10 because as the bottom triangle has 12 for bottom and 13 from top the top is off by 3 for both of them you just subtract by 3 and 12-3=9 and 13-3=10 plz give brainliest
7/8 is the answer hope this helps
