Answer:
Explanation: While people are not the only animals that alter their environment – think of beavers or termites – we tend to do it in much more -drastic and permanent ways. New York, Singapore, Hong Kong, once wild places thinly populated by hunter-gatherers, farmers, and fishermen, now are covered in concrete and rise with buildings hundreds of meters tall. The residents of those cities have certainly changed the physical structure of their communities over the past centuries in countless ways
Answer:
yes, mars, jupitet, saturn, neptune, venus, mercury, Uranus and earth
explanation: there's only 8 planets
A range of mountains along the pacific zone of volcanicity, the Andes, are as a result of tectonic plate processes caused by the subduction of the oceanic crust beneath the South American plate. Their rise is mainly attributed to the compression of the western rim of the South American plate, due to the subduction of the Nazca and Antarctic plates.
Answer:
D
Explanation:
The solution to the problem is 
How did we arrive at this:
We are going to use trigonometric ratios to solve this problem. The diagram of the sail forms a perfect and unique right angle triangle.
From the diagram, we can easily decipher the:
- hypotenuse axis
- opposite axis
- adjacent axis
From the given diagram, we know:
Adjacent axis and the opposite angle;
tan Ф = 
The unknown axis faces the opposite side;
Opposite = adjacent x tan Ф
Opposite = 2 x tan Ф
Note;
tan Ф = 1/ cot Ф
opposite = 2 x 1/ cot Ф
