1/10 you find a common denominator and add them together which is 36 and simplify it down
Angle C and E are supplementary angles and when added together equal 180 degrees.
To find E, subtract C from 180.
E = 180 - 147 = 33
Angle E = 33 degrees.
Using proportions, it is found that the differential equation which describes the growth of the pigeon population is given by:

<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, considering the initial population and the population one week later, the rate of growth is given by:
k = 9/6 = 1.5.
The standard differential equation for population growth is:

Hence:
