Two major problems associated with petroleum products are the environmental hazards associated with its extraction from the earth and also the environmental impact of its burning which emits greenhouse gases into the atmosphere which has been shown to cause global warming and climate change.
Answer:
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side).
The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²
a.
a=3, b=4 and c=5
a² + b² = 3² + 4² = 9 + 16 = 25 and c² = 5² = 25
25 = 25 ⇒ right triangle.
b.
a=5, b=6 and c=7
a² + b² = 5² + 6² = 25 + 36 = 61 and c² = 7² = 49
61 > 49 ⇒ аcute triangle.
c.
a=8, b=9 and c=12
a² + b² = 8² + 9² = 64 + 81 = 145 and c² = 12² = 144
145 > 144 ⇒ аcute triangle.

The hazards from the volcanoes include lava and pyroclastics, tephra and , lahars and climate alteration. Fertile soil and geothermal energy are beneficial results of volcanic eruptions. Much of El Salvador for example is convered with volcanic ash and this has been a fertile growing medium for coffee plants.
Explanation:
Developed Countries: Developed Countries have advanced economies, good infrastructure, and a high standard of living. Their markets will be highly regulated and high per capita income.
Emerging Countries: These countries will have a developing and manufacturing base with rudimentary infrastructures. Emerging countries are the suppliers of natural resources to the more advanced and developed countries. Their per capita income would be low as compared to developed nations.
Developing Countries: Developing countries economies are the same as the emerging countries.
