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:
There is a large number of volcanoes in the Pacific Ocean which continuously erupts when these volcanoes erupt they cause many earthquake in Ocean . it is dangerous because it can harm and destroy many ships and areas around that volcano
Explanation:
Answer:
<h2>Human activities contribute to climate change by causing changes in Earth's atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. ... Changing the atmospheric abundance or properties of these gases and particles can lead to a warming or cooling of the climate system.</h2>
Answer:
Its center is located near the town of Chicxulub
Explanation:
is an impact crater buried underneath the Yucatán Peninsula in Mexico.[4] Its center is located near the town of Chicxulub, after which the crater is named.[5] It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter,[2] the Chicxulub impactor, striking the Earth. The date of the impact coincides precisely with the Cretaceous–Paleogene boundary (K–Pg boundary), slightly less than 66 million years ago,[3] and a widely accepted theory is that worldwide climate disruption from the event was the cause of the Cretaceous–Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs.
