Question

find Pythagorean triplet of 20

Answer 1

Pythagorean Triplet =2m , m+1 , m-1 

2m=20 
m=20/2 
m=10 

m²+1=10²+1=100+1=101 
m²-1=10²-1=100-1=99 

Members are 20 , 101 ,99

Answer 2

Here is your answer
$2m = 20 \\ m = \frac{20}{2} \\ m = 10 \\ \\ {m}^{2} + 1 \\ {(10)}^{2} + 1 \\ 100 + 1 = 101 \\ \\ {m}^{2} - 1 \\ \\ {(10)}^{2} - 1 \\ 100 - 1 = 99 \: answer \: \\ \\ therefore \: \: the \: pythagoras \: triplet \: are \: 10 \:, \: 101 \: and \: 99.$
