Question

Find the Pythagorean triplet whose one number is 30.​

Answer 1

Answer:

General form of pythagorean triplets are m

2

−1,2m,m

2

+1

⇒First member of triplet a=2m=30⇒m=15

Since, it is even

⇒So, second member of triplet b=(m)

2

−1=15

2

−1=225−1=224

⇒And third member of triplet c=m

2

+1=225+1=226
