Write a short statement that expresses a possible relationship between the variables. (size of file, time to download the file)

So you may know that that the time for downloading a file  of Amb is B seconds, where A and B are numbers.

then if some file weights C, that is 10 times more than A, and you assume that the download speed sees this has downloading 10 times the Amb file The time for downloading this second file will be 10*B seconds.

This is an example of a linear relationship between the size of a file and the time to download the file.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
