Answer: angle 1 (choice A)</h3>
This is because angles 1 and 4 are vertical angles. Such angles form whenever we have an X shape like this. Vertical angles are always opposite one another and they are always the same measure. The fact that lines k and l are parallel has no relevance (so they could easily be not parallel and the two angles mentioned are still congruent).
If the 0 is in the numerator, the value is 0
if the 0 is in the denominator, the value is undefined
so 0/8 = 0
and 3/0 = undefined
