Answer:
6
Step-by-step explanation:
We can look that AB=BC=CD=18/3=6
So, AB = 6
Hello :

3060
times the negative: -3060
Answer:
The transversals cutting through the parallel lines create angles that are congruent to one another. Angles 1`and 5 are alternate interior and are congruent. Angles 2 and 6 are alternate interior and are congruent. And of course if 2 of 3 angles in 2 triangles are congruent, then the 3rd angles have to be congruent as well. HOWEVER, we can see that the sides are NOT congruent, and we need at least one side to prove congruency. Since we have 3 congruent angles, we can only say they are similar.
Step-by-step explanation:
x+y=12
x-y=4
Then you solve:
x+y=12
-y -y
x=12-y
x-y=4
+y +y
x=4+y
4+y=12-y
+y +y
4+2y=12
-4 -4
2y=8
divide both sides by 2 to isolate y
y=4
Plug it into one of the equations
x+4=12
-4 -4
x=8
