It is given that James has 5 friends who are available to go to a baseball game with him, but James has only has 2 extra tickets. This is a perfect example of a combinations question and we have been asked to choose 2 from a given 5. This can be spoken of as: Given 5 choose 2 and can be represented mathematically as a Combination:
Thus, James has 10 different choices to invite 2 friends.
In arithmetic, the Pythagorean hypothesis, otherwise called
Pythagoras' hypothesis, is a central connection in Euclidean geometry among the
three sides of a correct triangle. It expresses that the square of the
hypotenuse (the side inverse the correct edge) is equivalent to the whole of
the squares of the other two sides. The hypothesis can be composed as a
condition relating the lengths of the sides a, b and c, regularly called the
"Pythagorean condition": a^2+b^2=c^2
Since RAH is twice as large as EAC, all angles
have the same size, so they are similar.
RA = AEx2
