Denise and stacey went to a carnival. the admission fee was $6 per person. each ride at the carnival costs c dollars. the game booths charged g dollars for each game. both denise and stacey went on 7 rides each. stacey played 3 games, while denise played 2 games. which expression represents the total amount of money that denise and stacey spent at the carnival?

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
