Answer:
27, you need to simplify both sides of the equation to get x on one side.
Step-by-step explanation:
One answer (of several) would be 33: It's between 10 and 200 and the sum of its digits is 6. Continue this same pattern to identify other answers.
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
We use rulers obviously because the length of rulers are about 4 more times longer than hands. Hope this helps you :]
