Answer: South American plate and African plate
Explanation: Tristan de cunha is a volcano that has formed approximately 150 million years back when the plates namely, the African plate and the South American plate moved in the opposite direction. Due to this diverging plate motion, the Atlantic ocean was formed.
Tristan de cunha is a stratovolcano, having a total height of about 6000 m, of which, about 4000 m lies below the sea level and 2000 m lies above the sea level. It is located at about 500 km towards east of the Mid-Atlantic ridge. The volcano is surrounded by the lava flows and pyroclastic rocks that must have erupted from the volcano in the past.

Well, it is called the Ring of Fire. Anyways, I learned this some years ago so here you go, the answer! :D
Answer:
Since I don't have a list of answers, I can't pick on of the options for you. Can you give me the answers so I can choose the correct one? Thank you!
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
