The answer is 75

Step-by-step explanation:

All you need to do since angle C and F are congruent/same is make an equation with those numbers and solve for x

2.5x + 8 = 3.5x - 7

subtract 8 from both sides

2.5x = 3.5x - 15

subtract 3.5 from both sides

-x = 15

multiply both sides by -1

x = 15

Since angles A and D are both 90. And angles C and F are both 15. You add them to make 105.

Subtract 180-105 to get 75

step-by-step explanation:

(3rd option) - c

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.
