The diagram shows that ∠2 and ∠4 are the vertical angles.
<h3>What are vertical angles?</h3>
Vertical angles are the angles that are opposite of each other when two lines cross.
The statements are:
1. < 2 & < 4 are vert. angles
2. Lines M & N intersect at P
3. < 2 & < 3 are a linear pair
4. m < 2 + m < 3 = 180
5. <3 and < 4 are a linear pair
6. m < 3 + m <4 =180
7. m < 2 + m < 3 = m < 3 + m < 4
8. m < 2 = m < 4
9. < 2 =~ <4
Here are the reasons:
1. Given
2. Def of vertical angles.
3. Def if. Linear pair
4. Angle addition postulate
5. Def of a linear pair
6. Angle addition postulate
7. Substitution property
8. Subtraction property
9. Def of =~ angles.

Answer:
Climate change is a very bad problem caused by us humans. Our carbon footprint has caused polar ice caps to melt, sea level to rise, and weather to get hotter. Climate change is mostly caused by big factories that emit chemical smoke into the atmosphere. This change change is also caused by the carbon dioxide that is produced by cars. One way people could reduce climate change is by using electric cars or by taking the bus more often.
Explanation: Hope that helps :)
The correct answer is letter B. V-shaped Valley. It is the evidence that an area was once covered by a glacier. Glaciers form in an area where the temperature is so very low and stayed there for a longer time. Glaciers that reached the oceans form icebergs.
Answer: The following event shows an effect of human-led climate change in a tropical climate zone:
Higher temperatures cause drier conditions in the Amazon rain forest.
Explanation: The mean rise in the global temperature has directly resulted in the growing prevalence of loss of vegetation. This has, in turn, affected the average precipitation levels in the Amazon rain forest. Decreasing rains in the region have decreased the availability of the water making in reach negatives and it is thus intensifying drier conditions.
Answer:
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. ... Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time.
