Two horizontal lines are cut by a transversal. what is the least number of angle measures you need to in order to find the measure of every angle

You only need 1 angle measure if the lines are parallel, 2 if not

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.
