Answer:
i think 1 is 300 and 2 is -50
Step-by-step explanation:
sorry if im wrong
An obtuse angle is an angle that is in between 90 degrees and 180 degrees. It looks like this
I think its 52.3 yards but im not sure
One way is a simple random sample (SRS) which basically involves putting everyone's name into a hat and drawing out a list of names at random. Or the computer is the one doing the random selections.
Another way is to use cluster sampling. Each cluster would be the various stores. So if you had say 20 stores nationwide, then the company picks a few people at random from each cluster (store) and forms the sample that way. This method ensures that no store is left out, and could possibly be more representative compared to pure SRS which will pick any name at random. With SRS it is possible that some stores are over-represented while others are under-represented or simply represented not at all.

Side note:
An example of "over-representation" would be having a group of 90% males in a committee when the population at large is roughly 50% male, 50% female.
Under-representation is the complete opposite, so that example would be the 10% of females on the committee (when it should be closer to 50%)
Answer:
Alternate Interior Angles
Step-by-step explanation:
The angles are on opposite sides of the transversal and are in between the parallel lines. This means they are alternate Interior Angles. Additionally, this means they are congruent, so 15x=12x+15, which gives us x=5, and the measurements of the angles are 75° each.
