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.

Explanation:
A mineral is a naturally occurring, inorganic compound with a unique chemical structure and physical properties. A rock is a solid, stony mass composed of a combination of minerals or other organic compounds. For example, quartz and feldspars are minerals, but when formed together, they make a rock, granite.
The levels of greenhouse gases in the atmosphere have been increasing due to the widespread burning of fossil fuels by the growing human populations.
Answer:
In the past years, nature has been rapidly deteriorating due to human actions. One of the most prominent issues is deforestation. We as humans depend on trees to provide lumber, paper, and much more but at the same time trees also provide us with oxygen, prevent soil erosion, and provide a habitat for many species of animals.
The Amazon Rainforest is the home to billions of organisms and thousands of species. As we continue to destroy the habitat of these species, we are causing many of them to become endangered and even extinct. Though the death of a few birds or trees may not seem significant, everything in our planet is connected in some way. The extinction of one species can cause a major gap in the food web, impacting the entire ecosystem. For example, deforesting the habitat of birds will cause them to more easily be captured by their predators. The predator population will then grow exponentially, but because the bird population is decreasing the predator population will eventually die out. Since now there are no predators at all in the area for pests such as mice, these pests can no infest agricultural farms killing crops. Without these crops we humans cannot survive, so in the end us humans will be the ones impacted by our own actions. This example may seem like an exaggerated example to many, but when you take a look back at the major famines throughout history you will be able to see the trend.
It is understandable that many people depend on logging to make a living for themselves and their families. but other selfish people just want the best for themselves. In order to combat these two problems we must persuade governments to put harsher laws in place for those who illegally damage environment for their own benefits, and provide support to those whose jobs may be at risk due to environmental protection regulations. If the greedy are punished for their actions, it will keep them from deforesting more trees. As for the loggers, if the government can provide basic or vocational education to those people so they have the ability to work in other fields (can be related to logging like environmental protection or something different that won't harm the environment), then it will allow the people affected to smoothly transition to another style of living that won't harm the environment.
Explanation:
You first need to provide some scientific and specific evidence for what logging is doing to the environment for some credibility. Afterwards you need to explain <em>why</em> people should care about those impacts. Then in the end make sure to state the stakeholders and provide a few examples of how they can benefit from slowing down deforestation.
