Plzz answer first to answer will get brainlist which set of integers is not a pythagorean triple a)2,3,6 b)3,4,5 c)4,5,9 d)5,7,12

62 poin

There is only 1 Pythagorean triple b

a,c,d are not triples, they are not even a triangle

Step-by-step explanation:

There are 4  common Pythagorean triples.  They can all be proven using the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the  legs and c is the hypotenuse

(3, 4, 5), (5, 12, 13), (8, 15, 17) and (7, 24, 25) are the 5 common triples that should be memorized.

Lets check

a 2,3,6

2^2 +3^2 = 6^

4+9=36 this is not even a triangle

2+3 <6

The sum of 2 sides must be greater than the third

b)3,4,5

3^2 +4^2 = 5^2

9+16 =25

25=25  it is a triple

c)4,5,9

4^2 +5^2 = 9^2

16+25 = 81

39 = 81   This is not even a triangle

4+5 =9

The sum of 2 sides must be greater than the third

d)5,7,12

5^5 +7^2 = 12^2

25 +49 = 144

74 =144  this is not even a triangle

5+7=12

The sum of 2 sides must be greater than the third

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
