The volume of a cube with a side length of 1 foot is cubic foot, or
cubic inches. So, 1 cubic foot is equal to
cubic inches. The ratios of
cubic inches to
cubic foot and
cubic foot to
cubic inches can be used to convert between cubic inches and cubic feet.

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
