Answer:
The perimeter of the triangle is 2+√2
Explanation:
Since one of the angles of the triangle is 90°, the triangle in question is a right angled triangle.
Since two angles of the triangle are also equal, then two of the its sides will be equal.
Let the opposite and the adjacent sides of the triangle be 1. To get the hypotenuse side, we will apply the Pythagoras theorem which States;
Hypotenuse² = Adjacent²+opposite²
Hyp² = 1²+1²
Hyp = √1²+1²
Hyp = √2
The third side of the triangle is √2.
The perimeter of the triangle will be the sum of all its sides i.e 1+1+√2
= 2+√2
The perimeter of the triangle will be 2+√2
Well since a hundred board should go by 10's until you reach 100, start at 61 then go up 10 spaces and the answer is 71

Answer:
The Fertile Crescent was good for farming because of the fertility of its land, a result of irrigation from numerous large rivers in the region.
Advantages:
Irrigation and agriculture developed here because of the fertile soil found near these rivers. Access to water helped with farming and trade routes. Soon, its natural riches brought travelers in and out of the Fertile Crescent.
Disadvantages:
Since the world's earliest civilizations developed in the Fertile Crescent, it is not hard to imagine that there are many geographical advantages. The presence of two rivers and the sediment they leave behind after flooding made for successful crop surpluses. But the Tigris and Euphrates Rivers were also a disadvantage..
Answer:
1. Mining.
Mining affects the land by creating loss of biodiversity, sinkholes, mudslides and contamination. That’s just a few affects mining can have on the land.
2. Petroleum.
The main risk that happens when extracting petroleum are oil spills. Some of the worst oil spills in history have caused major fires, explosions, and contamination in the area where they are at. What’s worse is that innocent little animals get caught in those oil spills and die.
