Most everyday purchases at the store are labeled with the price of the item before sales tax. which expression could be used to find the amount of tax? amount of tax = original price + total cost amount of tax = (total cost)(original price) amount of tax = (original cost)(tax %) amount of tax = (total cost)(tax %)

Amount of Tax = (Original Cost)(Tax %)

Step-by-step explanation:

Amount of Tax = (Original Cost)(Tax %)

∠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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
