D. To prepare premium rates the amounts customers pay) for an insurance plan, an insurance company conducts an extensive risk study to
determine the probability that a member of a certain group may require
a pay-off. Based on these probabilities, the expected amount of payoff
is charged to the customer as part of the premium. Explain why car
insurance companies charge a higher premium for teenage drivers
with a clean driving record than for adult drivers with a clean driving
record.

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
