Let x represent the number of hours you read a book and y represent the total number of pages you have read. you have already read 70 pages and can read 30 pages per hour. write an equation relating x hours and y pages you read. then predict the total number of pages you will have read after another 3 hours.

rx and sx

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
