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 noun to which a pronoun refers is called the (B) antecedent.
It means to 'go before' in Latin, so the noun must come before the pronoun so it can refer to it.
The language of prose is typically straightforward without much decoration. Ideas are contained in sentences that are arranged into paragraphs. There are no line breaks.
Poetry is typically reserved for expressing something special in an artistic way.
