Remember, the sides are labelled with lower case letters, and angles are labelled with CAPITAL letters. The angles are labelled with the CAPITAL letter that is opposite from the side with that letter.
so:
Angle A is opposite side a
Angle B is opposite side b
Angle C is opposite side c
Secθ = cos^(-1)θ is the same as secθ = 1/cosθ

Answer:
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
Step-by-step explanation:
We will write the equation to represent this scenario.
Let x be the number of people who went for movies.
Then the price of ticket for x people will be: 6.25x
They spent $12 on refreshments and a total of $30.75 so the equation will be:

solving the equation will give us total number of people
So,

Hence,
The correct equation is: 6x+12 = 30.75
And 3 people went to the movies
It is A and B I think hope it helps
