The values that exist two standard deviations above and below the mean are 681 and 265.
<h3>How to determine the values?</h3>
The given parameters exist:
Mean = 473
Standard deviation =104
The values above and below the mean exist calculated utilizing:

In this case n = 2.
So, we have, 
The value above is:
x = 473 + 2
104 = 681
The value below is:
x = 473 - 2
104 = 265
Therefore, the values that exist two standard deviations above and below the mean are 681 and 265.

Answer: Angles 4 and 5
Step-by-step explanation:
Supplementary angles are angles that add up to 180. The only angle pairs the add up to 180 (you can tell by seeing if two angles are the only two on a straight line) are angles 4 and 5, and angles 3 and 4. Angles 3 and 4 isn’t an option, so it’s 4 and 5.
