Find m angle AFE.

Please I need help badly

It’s 173. Add all the given angles and so AFD is 116. Then you can see that angle DFE has the same angle marking as BFC which means they must have the same measure. So 116+57=173. Hope this helps.

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.

The answer is option c.
