In which scenario would someone want to use the paste link option?

a. jimmy is writing an email to his friend. he wants to copy and paste a graph that he made in a spreadsheet into his email to show his friend.
b. joyce is writing a paper on global warming. she copied and pasted a chart that she found in an online journal into her paper.
c. jack is making a slide show of pictures from his last vacation. he has been reviewing his pictures and copying and pasting the best ones for the slide show.
d. jamie is continually entering data on poverty rates around the country into a spreadsheet. she copied and pasted key parts of her data into her paper.

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
