Answer:
8
Step-by-step explanation:
y=1x+11
19=x+11
8=x
I have to do this for more characters
Step-by-step explanation:
y=107(vertically opposite angles)
x=180-107=73(angles on a straight line)
z=73(vertically opposite angles)
Step-by-step explanation:
To calculate a slope, we need to apply: 
Applying formula to each slope:
So, as you can see, there are equal pair of slopes, meaning that they are parallels, which<em> demonstrate that it's actually a quadrilateral figure.</em>
Answer:
C) Symmetric
Step-by-step explanation:
The symmetric property is the idea that if A = B, then B = A. Flipping the equation around doesn't matter.
It's like saying 2+3 = 5 is the same as 5 = 2+3. We can extend the symmetric property to not only deal with equations, but include congruence statements as well.
