Financial any specific behavior the studying of physical featuring of the Earth surface
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
Answer:
There are dried-up riverbeds on Mars.
Explanation:
Now there is some evidence that is known that in Mars there is some water in layers below the soil, that mean that there are some possible storage of water. The life in Earth as we know it, it is possible just with the presence of water, that is the reason of this important knowledge.
In Mars atmosphere is almost carbon dioxide (aprox. 95 %) and just some traces of water, so the main source is located in soil.
Answer:
Hey!
The dependent population of a country, otherwise noted to as the "non-employed sector", are the groups of citizens/inhabitants who are aged below 15 (school-attending) and above 60 (the elderly/retired people). Which have an effect on the economic value of the country, (they have no contribution to the economy)
