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


Examples of volcanoes the located along divergent plate boundries are Krafala volcano in Iceland and Erta Ale and Oldoinyo Lengai in africa.
By velocity, you are referring to the speed of sound. It can be modelled by the equation:
V = 331m/s + (0.6m/s/C) x T (where T stands for temperature and V stands for Velocity).
Plug in the numbers and you'll get 343m/s
Most likely on the are the region is located, like if its closer to the equator or not
