Aperson came to work at 8: 30 am, went out at 11: 45 am, had lunch, came in at 12: 30 pm, and left work at 5: 15 pm. the total number of hours worked by this person was

8 hours and 30 minutes ight.

Step-by-step explanation:

Some math and adding and stuff I did it in my head.

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.
