Answer:
75 degrees and 105 degrees
Step-by-step explanation:
Supplementary angles are those angles that sum up to 180 degrees
So angle A + B = 180 or B = 180 - A
then A/B = 5/7
7A = 5B
7A = 5(180 - A)
7A = 900 - 5A
12A = 900
A = 75
then B = 180 - A = 180 - 75 = 105

Step-by-step explanation:
Here are some notes i have from some sources i hope these notes will be able to help you achieve the grade you wanted to good luck!
-The bound on error of estimation, B , associated with a confidence interval is (z critical value) ·(standard error of the statistic) . ... Sample Size The sample size required to estimate a population proportion to within an amount B with 95% confidence is The value of may be estimated by prior information.
-P-value and margin of error are not same.
-A margin of error tells you how many percentage points your results will differ from the real population value. For example, a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time.
-The margin of error determines how reliable the survey is or how reliable the results of the experiment are. ... This is captured in statistics as margin of error. The higher the margin of error, the less likely it is that the results of the survey are true for the whole population.
-Population distribution means the pattern of where people live. World population distribution is uneven. Places which are sparsely populated contain few people. Places which are densely populated contain many people.
