In 1885 European leaders met at the infamous Berlin Conference to divide Africa and arbitrarily draw up borders that exist to this day. Lines of longitude and latitude, rivers and mountain ranges were pressed into service as borders separating the colonies.

The youngest age of the shale is 910 ka. According to the principle of inclusions, the shale formed before the tephra, so the tephra must be younger than 910 ka.
Hey there! I'm happy to help!
Edge cities are usually formed because land in the suburbs or on the outskirts of the city is cheaper (bid-rent curve), so they can make more a profit.
These businesses are normally connected the the CBD (central business district) so transportation to and from that area is still possible.
People that live in the suburbs or are visiting the main city have easy access to the edge city as you might not have to travel as far to these cities as the CBD (distance decay).
Edge cities can be a good thing because they allow for new businesses to thrive and they can increase economic activity and competition due to new construction, cheaper prices, new companies moving in, etc.
However, they can also be a detriment to the CBD because they might allow companies to relocate due to the cheaper land prices, they might take in the typical customers of the CBD companies, ultimately leading to the vacancy of the CBDs, which could be dangerous and create high-crime, unsanitary, or contaminated areas. It can also take attention away from significant or historical monuments and locations in the CBD.
Have a wonderful day and keep on learning! :D
Fertility rates and resources are connected because in areas where there are scarce resources and high fertility rates there will be problems in the ability to provide for the members of this hypothetical society. Therefore, individuals or animals could potentially live shorter and less healthy lives because of the lack of proper resources such as food, water, healthcare, or education.
Answer for first picture:
#1 = 43 degrees #2= 38 degrees
#3= 27 degrees #4= 45 degrees
Explanation for first picture:
All the angles are right angles. This means they all will equal 90 degrees! so if you take 90 degrees and subtract the one known angle you will have your answer! :)
Answer for 2nd picture:
#1 = X= 70 Y= 110
#2 = X= 102 Z= 102
#3 = X= 83 Y= 194
#4 = Y= 37 Z= 143
Explanation for second picture:
When you have angles like these the total will equal 360 degrees! look at the first pic, it shows 110 degrees, you also know that the angle across of it is equal to it. so together it equals 220 now subtract 360 - 220. you get 140. since you have two angles to figure out, you divide 140 into two. 140 / 2 = 70 degrees! you do the same steps for the rest of the problems!
( i am sorry for the bad explaining!)
