The continent which has 59% of the total population will have more than 5.31 billion people by 2050.
<u>Step-by-step explanation:</u>
It is given that,
- The total number of people is 9 billion.
- The estimated number of people in 2050 year is 5.31 billion.
Therefore, you need to find out which continent has the estimated number by finding the percentage value.
<u>To find what percent 5.31 is of billion is of 9 billion :</u>
Let x be the percentage to be calculated.
⇒ x percent of 9 billion is 5.31 billion.
⇒ (x/100) × 9 = 5.31
⇒ x = (5.31 × 100) / 9
⇒ x = 531 / 9
⇒ x = 59 %
∴ The continent which has 59% of the total population will have more than 5.31 billion people by 2050.

Answer:
2 - 
Step-by-step explanation:
Using the addition formula for tangent
tan(A - B) =  and the exact values
 and the exact values
tan45° = 1 , tan60° =  , then
 , then
tan15° = tan(60 - 45)°
tan(60 - 45)°
= 
=  
 
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 1 +  is 1 -
 is 1 -  
 
=  ← expand numerator/denominator using FOIL
