Anyone understand this it's similar triangles

First, we create a proportion to find the missing side.

Second, we set up an equation to solve for x in 3x - 3 by setting 15 and 24 equal to 3x - 3.

Finally, we solve the equation.

Our final answer is x = 14.

b

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
