The temperature in degrees fahrenheit can be estimated by counting the number of times a cricket chirps in one minute, dividing by 4, and then adding 37. according to this method, what is the temperature if a cricket chirps 84 times in one minute? plz meee

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
