Answer: 14, 17, 30
<u>Step-by-step explanation:</u>
In order to form a triangle, the sum of two sides must be GREATER than the third side for all combinations:
a + b > c & a + c > b & b + c > a
21 + 23 = 44 which is NOT greater than 44
2 + 3 = 5 which is NOT greater than 7
12 + 36 = 48 which is NOT greater than 53
14 + 17 > 30 & 14 + 30 > 17 & 17 + 30 > 14
so these side length form a triangle
