This graph shows how fast the International Space Station travels in orbit around Earth
What is the meaning of the point with an x-coordinate of 3?

A. In 1 second, the space station travels 3 miles.
B. In 3 seconds, the space station travels 15 miles.
C. The space station travels 3 miles in 15 seconds.
OD. It takes the space station 3 seconds to go 5 miles.

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.

i believe a. 12x≥120 is the answer

english maybe i can ..
