In a Northwest Washington County, speeding fines are determined by the formula: F
=
13
(
s
−
65
)
+
60

where
F
is the cost, in dollars, of the fine if a person is caught driving at a speed of
s
miles per hour.

If a fine comes to $255, how fast was the person speeding?

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
