Answer 1

$\huge{\boxed{\boxed{\underline{\rm{\purple{Answer}}}}}}$

Pythagorean triplets are 8, 15, 17

Step-by-step explanation:

We know that (2m, m² -1,m²+1 ) are pythagorean triplet.

Let 2m = 18

m= 8/2

m= 4

So the pythagorean triplet are

2m = 2× 4 = 8

m² - 1 = 4² - 1 = 4 × 4 - 1 = 16 - 1 = 15

m² + 1 = 4² + 1 = 4 × 4 + 1 = 16 + 1 = 17

∴ The pythagorean triplets are 8,15, 17

Checking

c² = a² + b²( where c is the largest number )

17²= 8² + 15²

289 = 64 + 225

289 = 289

Thus our answer is correct.
