What is the Pythagorean triple generator and how does it work?​
r-ruslan [8.4K]

Answer:

Step-by-step explanation:

The Pythagorean Theorem states that

a^2+b^2=c^2

or that the two legs added together squared equal the hypotenuse squared

not: this only works with right triangles

Now Pythagorean triples are the set of sides that follow that rule

an example would be 3,4,5

why is it a Pythagorean triple?

well because it follows

a^2+b^2=c^2

3^2=9\\4^2=16\\16+9=25\\5^2=25

25=25

If x2 + y2 = 38 and x - y = 2, then what is x? If there are two possible answers, then enter the larger of the two.
Ket [755]
If x-y=2 then x=2+y

And if you insert that in the first equation

(2 + y) {}^{2}  + y {}^{2}  = 38
4 + 4y + y {}^{2}  +  {y}^{2}  = 38
2y {}^{2}  + 4y - 34 = 0
y =  - 1 +  \sqrt{17}
Or
y =  - 1 -  \sqrt{17}


The first one is bigger so the answer is

y =  - 1 -  \sqrt{17}
