Answer: The length of third side is 15.
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The perimeter of given triangle is 44.
One side, suppose a is 18.
Second side, suppose b is 11.
Suppose, third side is c.
So the perimeter will be :
[tex]18+11+c=44[/tex]
[tex]29+c=44[/tex]
Subtracting 29 in both sides
[tex]29+c-29=44-29[/tex]
[tex]c=15[/tex]
Hence the length of third side is 15. Answer
