The inequality which best describe the third side of the triangle which has two sides of unit 20 and 31 is 20>b>31.
<h3>What is triangle inequality theorem?</h3>
Triangle inequality theorem of a triangle says that the sum of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus, according to this theorem,
(a+b)>c
(b+c)>a
(c+a)>b
The two sides of the triangle are 20 and 31. From the inequality theorem, the another side b can be represented as,
(20+31)>b
Thus, the length of b can be between 20 and 31.
20>b>31
Hence, the inequality which best describe the third side of the triangle which has two sides of unit 20 and 31 is 20>b>31 .

Answer:
- Africa is blessed with a rich bounty of natural resources. The continent holds around 30% of the world's known mineral reserves. These include cobalt, uranium, diamonds and gold, as well as significant oil and gas reserves.
- Over the period 2000 to 2008 resource extraction contributed more that 30 percent of Africa's GDP, while the annual flow of foreign direct has investment into Africa increased from $9 billion to $62 billion.
- Africa has been drawn a little benefit from this mineral wealth and remains one the poorest continents on the globe, with almost fifty per cent of the population living on less than $1.25 per day.
