Interior angles of a regular octagon all have the same measure of 135 degrees. So if angle BAH has measure 135, then angle BAP (which is supplementary to BAH) has measure 45. Similarly, BCP (congruent to BAH) is also of measure 45 degrees.
Next, since ABC has measure 135 degrees (congruent to BAH), so the corresponding external angle has measure 225 degrees.
Now, ABCP is a quadrilateral. For any quadrilateral, its interior angles sum to 360 degrees. We have three of these angles, so we can easily find the last, APC.

Answer:
The upper 20% of the weighs are weights of at least X, which is , in which
is the standard deviation of all weights and
is the mean.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation
, the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Upper 20% of weights:
The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then
The upper 20% of the weighs are weights of at least X, which is , in which
is the standard deviation of all weights and
is the mean.
