out of the following which is the pythagorean triplet a) 11,60,61 b)4,9,12 c) 10,24,27 b)5,5,2
Answers
Answer:
to be Pythagorean triplets.
Hypotenuse² = Base² + height²
Hypotenuse is largest side in triangle
(i)(3, 5, 4) iff 5² = 3² + 4² => 25 = 9 + 16 => 25 = 25 - True
(ii)(4, 9, 12) iff 12² = 9² + 4² => 144 = 81 + 16 but 144 ≠ 97 so False
(iii)(5, 12, 13) iff 13² = 12² + 5² => 169 = 144 + 26 =>169 = 169 - True
(iv) (24, 70, 74) iff 74² = 70² + 24² => 5476 = 4900 + 576 =>5476 = 5476 - True
(v)(10, 24, 27) iff 27² = 24² + 10² =>729 = 576 + 100 but 729 ≠ 676 so False
(vi)(11, 60, 61) iff 61² = 60² + 11² => 3721 = 3600 + 121 =>3721 = 3721 - True

Step-by-step explanation:
a) 11 , 60 , 61
- 61² = 3721
- 11² = 121
- 60² = 3600
:. 3600 + 121 = 3721
- (a) 11 , 60 , 61 is a Pythagorean triplet ✅
_______________________________
b) 4 , 9 , 12
- 4² = 16
- 9² = 81
- 12² = 144
:. 16 + 81 = 97 ≠ 144
:. 4 , 9 , 12 are not Pythagorean triplet
________________________________
c) 10 , 24 , 27
- 10² = 100
- 24² = 576
- 27² = 729
:. 100 + 576 = 676 ≠ 729
:. 10 , 24 , 27 are not Pythagorean triplet
_________________________________
d) 5 , 5 , 2
- 5² = 25
- 5² = 25
- 2² = 4
:. 25 + 4 = 29 ≠ 25
:. 5 , 5 , 2 are not Pythagorean triplet
