Answer 1

Answer:

12, 17, 30.

Step-by-step explanation:

Given

(a) to (d)

Required

Which cannot represent a triangle

The rule to use is:

$a + b > c$

So, we have: 12, 17, 30.

$12 + 17 > 30$ ===> $29 > 30$ --- False

$12 + 30 > 17$ ==> $43 > 17$

$17 + 30 > 12$

Because, one of the inequalities is False, then this can not represent the sides of a triangle.
