Maura writes an expression equivalent to 8a 2 (23 2 5a) 2 2a. Her work is shown below. 8a 2 (23 2 5a) 2 2a Step 1: 8a 1 3 2 5a 2 2a Step 2: (8a 2 5a 2 2a) 1 3 Step 3: (3a 2 2a) 1 3 Step 4: a 1 3 In what step does Maura make a mistake? Describe her error and find the correct equivalent expression.

the answer is c. hope this !

step-by-step explanation:

is there a question here?

step-by-step explanation:

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.
