✪ Question ✪

Find the Pythagorean triplet in which one number is 20.

✪ To find ✪

The Pythagorean triplet.

✪ Pythagorean Triplet ✪

A Pythagorean Triplet with x:-

{2m, (m²-1), (m²+1)}

✪ Solution ✪

Consider that 20 is the smallest member of the triplet.

According to the triplet with m,

2m = 20

So,

2m = 20

⇒m = 20/2

⇒m = 10

So, m = 10.

• (m²-1)

= (10²-1)

= (100-1)

= 99

• (m²+1)

= (10²+1)

= (100+1)

= 101

✪ Hence ✪

2m = 20

(m²-1) = 99

(m²+1) = 101

✪ Therefore ✪

The Pythagorean triplet in which one number is 20 is (20, 99, 101).
