Find the value of x and y. Need some help solving this one.

x is 45, y is 80

Step-by-step explanation:

subtract the angles surrounding x (70 - 25 = 45)

add 45 + 55 to get 100
the entire triangle has to equal 180 degrees, so subtract 100 from 180 to get the value of y

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.
