Sum of acute angles are always 90 degree.
Here, ratios = 7 + 11 = 18
Value of 1 ratio = 90/18 = 5
So,acute angles are: 7(5), 11(5) = 35, 55
In short, Your Answer would be 35, 55, 90

Answer:
Weights of at least 340.1 are in the highest 20%.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

a. Highest 20 percent
At least X
100-20 = 80
So X is the 80th percentile, which is X when Z has a pvalue of 0.8. So X when Z = 0.842.




Weights of at least 340.1 are in the highest 20%.
y = x^2 + 1
y equals x squared plus 1
y = 4^2 + 1
y = 16 + 1
y = 17
