Constant rate of 12 blocks and 6 minutes

12 blocks per 6 minutes

So then:

2 blocks per 1 mintue

(12 / 6 = 2)

(not sure if you had an actual question, but here's a unit rate)

are you an artist's daughter? cuz dang you a fine piece of art, girl.

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
