How is the following decimal number read? 28.9 a. twenty and eight-nine tenths b. twenty-eight and nine hundredths c. twenty-eight and nine tenths d. twenty-eight nine

C. Twenty-eight and nine tenths.

Step-by-step explanation:  

We have been given a decimal number . We are asked to choose the correct option that represents how to read our given decimal number.

Upon looking at our given decimal number we can see that it has one digit at tenth place that is 9, which represents that our number has 9 tenths.  

The two digits before decimal are 2 (tens place) and 8 (ones place). These digits make 28.

Therefore, the given decimal number could be read as twenty-eight and nine tenths and option C is the correct choice.

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.
