The two angles marked are congruent.
That is one pair of congruent angles. -------> A
Then the vertical angles are congruent.
That is a second pair of congruent angles. -------> A
Finally, we have the two sides marked congruent.
That is one pair of congruent sides. ------> S
Put together what we have above, and it gives us AAS.
Answer:

Step-by-step explanation:
Let
be the length of the longer side of the smaller rectangle and
be the length of the shorter side of the smaller rectangle
When you look at the combined rectangle from top to bottom, you can see that
. Therefore, 
This is the same for
. Thus, 
When you look from right to left, you can see that
. Using this, we can represent
in terms of
.

Now, we can find the ratio of
:

Answer: D: x = {-3, -1, 1}
<u>Step-by-step explanation:</u>
Domain refers to the x-values of the coordinates.
Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.
(-3, -2) --> x = -3
(-3, 0) --> x = -3 <em>already listed above so no need to list it again</em>
(-1, 2) --> x = -1
(1, 2) --> x = 1
the x-values are: -3, -1, & 1
so the domain is: x = {-3, -1, 1}
27 divided by 9% (0.09), = 300. So, the answer is 300.
