Thank you for the opportunity to help you with your question!

a=8cm b=14 cm

the third side must be bigger than the difference 

c> b - a 

c> 14 cm - 8 cm

c > 6 cm


the third side must be 

smaller than the sum

c < b + a

c < 14 cm + 8 cm

c< 22 cm

therefore answer is:

22 cm

Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
