Directions: Find the value of each variable.

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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
