Trent wanted to know if there was a connection between his coffee consumption and how well he slept that night.

for weeks, trent recorded how many cups of coffee he drank in the morning and how many hours he slept that night. the probability that a day is one when he drank exactly 1 cup of coffee is 0.71, the probability that it is one when he slept exactly 8 hours is 0.61, and the probability that it is one when he drank exactly 1 cup of coffee or is one when he slept exactly 8 hours is 0.89.

what is the probability that a randomly chosen day is one when he drank exactly 1 cup of coffee and is one when he slept exactly 8 hours?

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.
