Acircle is divided into 9 equal parts. what is the angle measure of two of those parts?

There are 360 degrees in a circle. That means that we first divide 360 by 9.
360/9=40
We have the measure for one of the nine parts of the circle, but we need two. All we do is multiply 40 by 2 to get 80 degrees.

:)

80 degrees cause you divide 360 by 9 which equals 40 and multiply that by 2

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
