As per convention:
- the angle at A is named A, the angle at B is named B, and the angle at C is named C
- the side of leght a is the side opposed to A, the side of length b is opposed to B, and the side of length c is opposed to C.
Now just state the law of cosines:
c^2 = a^2 + b^2 - 2ab cos(C)
Also, a^2 = c^2 + b^2 - 2bc cos (A)
And, b^2 = a^2 + c^2 - 2ac cos (B)

The direct characters in The Cask of Amontillado are Montresor (the first-person narrator) and the ironically-named Fortunato, his inadvertent enemy. No one else appears in the story, but reference is made to several indirect characters.Luchesi is a man known to both Montresor and Fortunato.

Montresor uses repeated references to Luchesi as a form of reverse psychology to lure Fortunato into the vaultMontresor's disobedient servants are also mentioned. We do not know how many there are, but the fact that he has several makes us question his claim to be a ruined man. He has expressly told them to stay in the house and is cynically certain that this is the way to ensure their departureLady Fortunato is mentioned by her unfortunate husband. She will be waiting, in company, at the palazzo.
