Using the same information from Problem 1, suppose that 68 adult tickets were sold. Use your equation above to determine how many student tickets were sold.

Step 1: Set up a table with quantity and value.

Step 2: Fill in the table with information from the question.

Step 3: Add down each column to get the equations

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
