Jack can read 45 pages of his book in one and a half hours. At that rate, how long will it take hm to
read the entire 300-page book?

10 Hours

Step-by-step explanation:

First take 45 and multiply by two to get 90 pages every 3 hours.

Divide 90 by 3 to get how many pages read each hour which is 30 pages an hour.

Divide 300 pages by 30 pages to get 10 hours.

it should be a and d. lmk if i'm wrong xd

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.
