Answer:
<em>See explanation</em>
Explanation:
Given
Represent the vertical angle with 

The question has incomplete details because the length of the ladder is not given; neither is the distance between the ladder and the wall given.
<em>See attachment for illustration</em>
So, this solution will be based on assumptions.
Represent
- The height from ground to the top of the ladder with y
- The length of the ladder with L
- The distance between the ladder and the wall with x
Carla could solve for y in any of the following ways:
1. Tan formula

In this case:

Multiply both sides by y


Divide both sides by tan


This can be used if the distance (x) between the ladder and the wall is known.
Assume x = 15


2. Cosine formula

In this case:

Multiply both sides by L




This can be used if the length (L) of the ladder is known.
Assume L = 15


The correct answer choice would be the third one: "Homer writes that Odysseus and his men 'were left to groan and wait for morning' (218)." In MLA, the period needs to be outside of the parentheses, not inside the parentheses or the quotation. So that leaves us between choices 2 and 3. Well, it isn't the second one because the way they cited it (Homer: 218) isn't correct, they should have written it as (Homer, 218). Therefore, the third one seems to be the most correct. Hope this helped some :)
