Answer:
Option B
Step-by-step explanation:
In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So
[tex]5 + 12 > k[/tex]
[tex] = > 17 > k[/tex]
Hence the measure of k is less than 17.
In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.
Atlast , the range of k is :-
[tex]7 < k < 17[/tex]
