Acrane is lowering a concrete block from a height of 270 feet above the ground at a constant rate 2.5 feet per second. which function can be used to determine h, the height, in feet, above the ground of the concrete block after 5 seconds?

answer: i think it's a

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
