To determine if the set of numbers 13, 15, 18 is a perfect triple, we need to check if one number is the sum of the squares of the other two numbers.
Let's calculate the squares of the numbers:
13^2 = 169
15^2 = 225
18^2 = 324
Now, let's check if one number is the sum of the squares of the other two numbers:
Is 169 + 225 = 18^2?
Is 169 + 324 = 15^2?
Is 225 + 324 = 13^2?
From the calculations, we can see that none of the numbers are the sum of the squares of the other two numbers. Therefore, the set of numbers 13, 15, 18 is not a perfect triple.
The answer is B) No.
