∠bcd is reflected over the x-axis. if m∠bcd = 35°, what is the measure of ∠bʹcʹdʹ?

35°

55°

135°

145°

A reflex angle is the larger angle and in this problem, it happened that ∠BCD reflected from x-axis with the angle of 35°. It is being asked that was is the angle of ∠B'C'D and the answer is 145°. The solution is we only subtracted 35° to 180°.

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.
