Answer:
<u><em>-71</em></u>
Step-by-step explanation:

so 4/5 of A is really 80% of A then.
since a whole A is 100% of A, 100% - 80% = 20%, A is being reduced by 20%, namely 1/5.
I want more points next time....Hehehee!

The four answer choices are equal and pass through the point (-3,1), which you verify replacing the variables:
y - 1 = (x + 3)
1 - 1 = -3 + 3
0 = 0.
The other factor that you have to considerate is the slope.
The slope of the equation y - 1 = x + 3 is 1 (the coefficient of the x).
Given that the slopes of two parallel line are the same (equal), you need to determine the slope of the parallel line.
Once you know the slope of the parallel line, you can choose the right option.
The equation shown, y - 1 = x + 3 is the right fit if and only if the parallel line has slope 1.
Supplementary angles add to 180 degrees.
x+8x=180
9x=180
x=20
Find the supplement of an angle of 20 degrees
180-20=160
Final answer: 160 degrees and 20 degrees respectively
