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
