Professor Blanchard is packing up the books in he office to move to a new location. A small box can hold 44 books and a large box can hold 30 books. In total, these boxes must hold at least 455 books, which is the total number of books in the professor's office. Write the inequality in standard form that describes this situation. Use the given numbers and the following variables.
x = the number of small boxes
y = the number of large boxes

x=10

y=20

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
