Answer:
∠9 and ∠12
Step-by-step explanation:
Supplementary angles are two angles that add up to 180. Looking at all the answer choices, A, C, and D have either Big-Big angle or Small-Small angle. What we need is Big-Small angle that is next to eachother, which is ∠9 and ∠12.
Hope this helped.

Answer:
The system has two distinct solutions.
Step-by-step explanation:
The given system of equations are:

and

In order to determine the number of solutions the two equations have, we need to equate the two equations to obtain,

We now group all terms on the left hand side and equate everything to zero.


This is now a quadratic equation in
with
.
At this stage we check the number of solutions using the discriminant.


Since the discriminant is greater than zero, the equation will have two distinct roots.
Therefore the system of equations has exactly two distinct solutions.
If you wish to see these solutions, you can continue as follows;
We factor
to obtain,



When 
Then we have,

When 
Then we have,
