Find 
First, calculate 
--- angle on a straight line
So, we have:
Collect like terms
Next, calculate PQR
So, we have:
Collect like terms
So, PRO is calculated as:
--- angles in a triangle
So, we have:
Collect like terms
Answer:
7
Step-by-step explanation:
1. Lets Combine Like Terms. The only combineable terms are 8 and 8. So if we combine them they will equal 16. And we will have (2n+2)=16
2. Let's isolate the variable. We can do this by subtracting 2 from both sides. This will come out to 2n+14.
3. Let's further isolate the variable. We can do this by dividing both sides by two, which will finally come out to n=7

Answer:
C
Step-by-step explanation:
Answer:
Undefined.
Step-by-step explanation:
Slope = (y2 - y1)/(x2-x1)
Values of x are the same, so x2 - x1 = 0 - 0 = 0
Slope = (y2 - y1)/0
So, slope undefined.
For vertical line, slope is always undefined.
