Find The value of x. Then find the measure of each labeled angel

x=20 the angles are 80 and 100

Step-by-step explanation:

those types of angels are supplementary, so we can set up an equation like this: 5x+4x=180

We'll get x=20, then we can put 20 into each angle to find out its measure:)

5(20)=100

4(20)=80

1; 35 is the ratio

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.
