Answer:
PART A:
Line m: 1/2x + 6
Line n: 1/2x - 3
PART B:
The slope is the same in both lines
The slope is -4. This is because of slope intercept form, y=mxtb. M= the slope so the slope in this case is -4
Answer:
Exact form: 
Decimal form: 
The solution for x is: The solution for x is of 10.455º
Step-by-step explanation:
We are given the following equation:

Placing into the desired format, the exact format is:

In the decimal part, we divide 8 by 9. So

Solving for x:
We apply the inverse sine. So




The solution for x is of 10.455º
