Answer:
A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula: c^2 = a^2 + b^2 or c^2 = x^2 + y^2 where, c is the hypotenuse of the triangle and is the side opposite to the 90° angle while a and b are the sides adjacent to the 90° angle.
In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y: y^2 = c^2 – x^2 y^2 = 5^2 – 2^2 y^2 = 21 y = 4.58
Explanation:
The natural number is the number before the decimal. Therefore the answer is: y = 4
Answer:
through glacial deposits and ice cores
Explanation:
Scientists use ice to study ancient climates through glacial deposits and ice cores.
These two sources are fundamental to the study of ancient climates whose salient information has been preserved and locked in time through glacial deposits.
- A place can remain frozen for an extended period of time.
- Some gas bubbles can be trapped in the midst of ice being formed.
- These bubbles and compacting sequences of ice layers are used to interpret ancient climates.
- Ice cores are drilled an collected in barrels where they are taken to the laboratory for further studies.
- It is possible to even date each ice layer.
So, the solution is through glacial deposits and ice cores.
Answer:
Drought- A prolonged period of abnormally low rainfall, leading to a shortage of water.
Desertification- The process by which fertile land becomes desert, typically as a result of drought, deforestation, or inappropriate agriculture.
