Answer:
B.
cm,
cm,
cm
Step-by-step explanation:
we know that
The <u>Triangle Inequality Theorem</u>, states that the sum of the lengths of two sides of a triangle must always be greater than the length of the third side
so



where
a,b,c are the lengths sides of the triangle
case A)
cm,
cm,
cm
Let



Verify
------>
------> is true
------>
-------> is not true
therefore
The three lengths of case A) could not be the lengths of the sides of a triangle
case B)
cm,
cm,
cm
Let



Verify
------>
------> is true
------>
-------> is true
----->
--------> is true
therefore
The three lengths of case B) could be the lengths of the sides of a triangle
case C)
cm,
cm,
cm
Let



Verify
------>
------> is true
------>

--------> is not true
therefore
The three lengths of case C) could not be the lengths of the sides of a triangle
case D)
cm,
cm,
cm
Let



Verify
------>
------> is not true
therefore
The three lengths of case D) could not be the lengths of the sides of a triangle
