You are buying a new internet service. the service costs $75 per month. in the equation below, d is the total number of dollars that you pay for your service, and t is the time (in months) that you keep the service. the relationship between these two variables can be expressed by the following equation: d = 75t identify the dependent and independent variables. the total number of dollars you pay (dependent / independent variable) the time in months you keep your service (dependent / independent variable)

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.
