States from 1963 to 2992 by 0.5% each year. In
1963 there were 41 million acres of Ponderosa
Pine forests.
A. Write a function that models the above data
over time,
B. To the nearest tenth, about how many
million acres of Ponderosa pine forests are
left in 2020?

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
