Mark is listening to his radio and tunes it to the frequency represented above. which equation can mark use to describes the graph for the frequency of the radio? a 3cos(π2x) b 3sin(πx) c 3sin(π2x) d 6sin(π2x)

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

a 360 degree rotation
