<h3>
Answer: y = 78</h3>
==================================
Justification #1: Angle x is 78 degrees as these two angles are corresponding angles (congruent due to the parallel lines). We also know that y = x because they are vertical angles. So by the transitive property, y = 78
Justification #2: The parallel lines mean that the alternate exterior angles are congruent, so y = 78 through one step (instead of multiple steps in the prior justification)
The answer is B,
see explanation in the attached picture
The solution would
be like this for this specific problem:
ab/a+b = c
b = -1 + a
for c:
<span>(5(-1 + 5))/(5 + (-1 +5))
</span><span>5(4)/ 5 + 4
</span><span>20 / 9
</span>
<span>The correct
answer between all the choices given is the first choice or letter A. I am
hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.</span>
