Tina is ordering a pair of shoes that cost $123.99. if the sales tax is 8% and the shipping is $19.99, what is the total cost?

$153.90.

Step-by-step explanation:

We have been given that Tina is ordering a pair of shoes that cost $123.99. The sales tax is 8% and the shipping is $19.99. We are asked to find the total cost of the shoes.

Let us find 8% of $123.99 as:

Total cost of shoes would be original cost plus sales tax plus shipping charges.

Therefore, the total cost of shoes would be approximately $153.90.

∠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.

the correct answers i think are b. and d.

give me brainliest if it is correct!
