To Euclid, a postulate is something that is so obvious it may be accepted without proof.
A. A straightedge and compass can be used to create any figure.
That's not Euclid, that's just goofy.
B. A straight line segment can be drawn between any two points.
That's Euclid's first postulate.
C. Any straight line segment can be extended indefinitely.
That's Euclid's second postulate.
D. The angles of a triangle always add up to 180.
That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."
Answer: B C
The 8% of $289.90 is $23.192 so the sales tax on television will be $23.192.
The percentage is the same as the amount of that value, but it is expressed as a number between 1 and 100, and it may be used to make predictions. For instance, if you say 678, we must also know the whole number, but if you say 80%, the situation is apparent.
As per the given,
Cost of the television = $289.90
Sale tax = 8% of $289.90
Sale tax = (8/100)289.90 = $23.192
Hence "The 8% of $289.90 is $23.192 so the sales tax on television will be $23.192".

Without specific data, we cannot provide a distance in miles between Joe's home and the park. However, note that distance measurements can be converted from kilometers to miles using the conversion factor 1 mile = 1.61 km. Ensure to round off figures to the nearest tenth for precision and accuracy.
Unfortunately, the question does not provide enough information to determine the distance in miles between Joe's home and the park. However, we can discuss generally how you might find out such information. For instance, if you have the distance in kilometers, you can convert it to miles using the conversion factor 1 mile = 1.61 km. So to convert kilometers to miles you divide the distance in kilometers by 1.61.
Remember when dealing with distance, you should also pay attention to the precision and accuracy of the measurements you make. Round off these numbers to the nearest tenth as directed in the question for clarity and ease of comprehension.
