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
