The Pythagoras theorem for a right triangle is
c^2 = a^2 + b^2 where c = hypotenuse and a, b are the legs of the triangle.
3 positive integers which fit this formula are called Pythagorean Triples.
3,4 5 are a triple because 5^2 = 3^2 + 4^2 ( 25 = 9 + 16).
and also 17^2 = 15^2 + 8^2 ( 289 = 225 + 64).
Step-by-step explanation:
Pythagorean theorem is [tex]a^{2} + b^{2} =c^{2}[/tex] (c being the largest number)
Pythagorean triples are 3 positive numbers that make this equation true.
let's start with 3,4,5
3²+4²=5²
9+16=25
25=25
Since it's true, it's a triple.
Now 8,15,17
8²+15²=17²
64+225=289
289=289
This is also true, so it's also a triple
Hope this helps!

Answer:
C, 2000
Step-by-step explanation:
First convert kilo grams into grams, there are 1000 grams in 1 kilogram, the prefix "kilo" means thousand. if you multiply 5.1 times 1000 you will get 5100 grams in the bag. Divide this by the weight of the penny, 2.5, to get 204. The question asks "About how many pennies are in the bag?" so we know to round to the closest answer being c.
