Question

To 5, 7, 9 a
Justify.
Pythagorean triplets) why ?​

Answer 1

Answer:

Pythagorean triplets

a2+b2=c2

then,5,7,9

5square+7square=9square

25+49=81

74=81

:5,7,9 are not Pythagorean triplets

Answer 2

To verify Pythagoras triplets..

The sum of square two triplets is equal to the square of third triplets.

$9 {}^{2} = 5 {}^{2} + 7 {}^{2}$

81= 25+49

81= 74

So the sum of square of two sides is not equal to the square of third side..

So 5,7,9 are not triplets..
