To keep in shape, Meg exercises at a track near her home. She requires 40 minutes to do 8 laps running and 6 laps walking. Assuming she maintains a consistent pace while running and while walking, how long does Meg take to complete a lap

Step-by-step explanation:

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
