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)

What dramatic effect does Shakespeare create by pairing the emotions of love and hate in the first act of the play?
aliina [53]

Answer:

Love, hate and honour

Explanation:

There are many components of Shakespeare’s classic, ‘Romeo and Juliet’, which mainly consist of love, hate and honour. This is the story of the incessant love of two young people, which crosses the borders of family and convention. It encompasses love, hate and tons of emotion, tragically ending with the harsh reality of death.

There are many imperative events leading up to various other events that take place in this specific scene. Possibly the most important and the utmost obvious fact that the audience discern about is about the two families, The Capulets and The Montagues.
