What is the formula for Pythagorean's Theorem?
Pythagorean's Theorem is used if you know the length of two sides of a triangle and wish to know the length of the third. The formula is: a^2 + b^2 = c^2, where a and b represent the lengths of the triangle's legs, and c represents the length of the hypotenuse. (You can rearrange the formula to solve for whichever variable you need.)

If President Woodrow Wilson was the founding creator of the League of Nations after World War I, why was the USA not a part of it?
Although President Wilson came up with the League of Nations, the US Congress needed to approve America's joining of the League. After much discussion, Congress came to the conclusion that they did not want to be involved with what they viewed as Europe's affairs, especially after Americans suffered casualties during the first World War, and wanted to continue their practicing of isolationist policy.
What is the difference between "it's" and "its" and how do I know when it is appropriate to use each word?
"It's" is a shortened form of the phrase "it is", and if you're having trouble knowing if "it's" is correctly being used in your sentence, write out the complete phrase in place of the contraction and see if it fits. If it doesn't, chances are the correct spelling is "its", which is the possessive form of "it". Here's are examples of both being used correctly: I love dark chocolate because I love its rich flavour. Do you know what the time is? It's twelve o'clock.
