Answer:
Reference angle: 
is not defined.
Step-by-step explanation:
The angle 
goes from the positive x-axis to the negative y-axis.
Therefore the reference angle can be calculated as following:
We know that 
is:
If 
then 
, therefore 
is not defined, because the division by 0 is not defined.

Word Problem</h2>
To form equations from word problems, we can do the following:
- Identify variables
- Find key information
- Identify word equations and translate into numerical equations
- Solve
<h2>Solving the Question</h2>
We're given:
- Let <em>x</em> be the number of individual tickets that were sold
- Let <em>y</em> be the number of group tickets sold
- Cost of 1x = 7 dollars
- Cost of 1y = 16 dollars
- Baseball team: 36 more x than y
⇒ x = 36 + y - Fundraiser raised 574 dollars in total
⇒ 7x + 16y = 574 dollars
Question: How many individual tickets were sold? (What is the value of <em>x</em>?)
Here are all the equations we have created:
We can solve for the value of <em>x</em> using systems of equations.
First, isolate <em>y</em> in the first equation:
Now, plug this into the second equation:
Therefore, <em>x</em> is equal to 50.
<h2>Answer</h2>
50 individual tickets were sold.
x - 3y =2
2x+ y =11 | *3
x - 3y = 2
6x +3y=33
--------------
7x =35
x=35:7
x=5
x-3y=2
5-3y=2
3y=5-2
3y=3
y=1
