Answer:
3 Triples
Step-by-step explanation:
To check if it is a right triangle, the sum of the square of the two smaller numbers must be equal to the square of largest number.
Check (27, 36, 45)
27² + 36² = 2025
√2025 = 45
Therefore, this is a right triangle.
Check (12 ,17, 20)
12² + 17² = 433
√433 = 20.81
Therefore, this is NOT a right triangle.
Check (24, 32, 40)
24² + 32² = 1600
√1600 = 40
Therefore, this is a right triangle.
Check (14, 48, 50)
14² + 48² = 2500
√2500 = 50
Therefore, this is a right triangle.
There are 3 triples.
