Answer:
12, 17, 30.
Step-by-step explanation:
Given
(a) to (d)
Required
Which cannot represent a triangle
The rule to use is:
[tex]a + b > c[/tex]
So, we have: 12, 17, 30.
[tex]12 + 17 > 30[/tex] ===> [tex]29 > 30[/tex] --- False
[tex]12 + 30 > 17[/tex] ==> [tex]43 > 17[/tex]
[tex]17 + 30 > 12[/tex]
Because, one of the inequalities is False, then this can not represent the sides of a triangle.
