The measure of a single angle of a triangle is not enough information to allow you to find any other angle or side length of the triangle. Is there more information or a figure?
If this triangle is a right triangle, and angle C is the right angle, then angle C measures 90.
The sum of the measures of the angles of a triangle is 180.
m<A + m<B + m<C = 180
We know angle A measures 48.
Angle C measures 90.
48 + m<B + 90 = 180
m<B + 138 = 180
m<B = 42
It will take 29.4 years for the population of Africa to be two times what it is today. This reflects: doubling time.
Doubling time is the time it takes for a particular amount of size or value to double at a given growth rate. By applying the 70 rules, we can find the doubling time of the exponentially increasing population. To do this, divide 70 by the growth rate (r).
Rule of 70 is a simplified way to determine the doubling time using the equation doubling time = 70 / r. Where r is the percentage growth rate of the population. For example, if the population of 10 species increases by 2 individuals per year, the r value will be 20%.
