Answer:
8, 15, and 17
Step-by-step explanation:
Given:- One of the triplets is 15
To find:- other 2 numbers of the triplet
Proof:-
We know that Pythagorus theorem is of the form
2m, m² - 1 and m² + 1
where m is an integer but not negative
Now, we know that out 2m, m² - 1, m² + 1 one of these must be equal to 15
Because 15 is one of the other triplets
So, let's find which corresponds to 15 and thus finding the value of 'm'
Let's say,
2m = 15, then
m = 15/2
But we said that m is an integer which is not negative
so, 2m isn't equal to 15
Now, let's say
m² - 1 = 15 then
m² = 15 + 1 = 16
m = 4
I am not taking negative because I said that m is an integer which is not negative so, m = 4
Now, we can use m = 4 to set up the triplets
2m = 2 × 4 = 8
m² - 1 = 4² - 1 = 16 - 1 = 15
m² + 1 = 4² + 1 = 16 + 1 = 17
So, the Pythagorean triplets in which one member is 15 are
8, 15, and 17
Hope it helped and you understood it........All the best
