The value of x is 108°

Step-by-step explanation:

Given interior angles of parallelogram are:

The sum of interior angles of a parallelogram is 360°.

We will use this information to find the value of x.

So adding up all the angles and putting the sum equal to 360 we get,

Taking LCM on left side of the equation, as it involves fraction

Multiplying both sides by 3

Dividing both sides by 10

Hence,

The value of x is 108°

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.

just a girl thing, i think im cute when im not lol
