A. Convert 74.35° to degree, minute and second

74°21'

Step-by-step explanation:

DMS Form:

The given angle is 74.35°

The whole number part is the degree so we don't need to change that. While, the decimal part would be multiplied  by 60 to convert it into minutes.

=> 74° + (0.35 × 60)

=> 74° + 21'

Since, the minute form has already been changed into a whole number and it doesn't contain any further decimal part, so we won't change it further to seconds. So, our answer will be

=> 74°21'

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.
