15. Which set of numbers forms a Pythagorean triple? 20, 25, 50
O 15, 17, 21
O 11, 60, 61
O 5, 10, 15

yes

step-by-step explanation:

part a: 1.08

part b: 27.59

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
