Step-by-step explanation:
I think this you can do this .
Prime numbers are: 37, 47, 19,
Composite numbers are: 9, 15, 26, 33, 45
Answer:

Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>

Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=> 
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
