First image represents the complementary angles , as their sum is 90⁰

Second image represents the supplementary angles , as their sum is 180⁰

1) complementary angles

2) supplementary angles

Step-by-step explanation:

1)

25  + 65 = 90

therefore given angles are complementary angles

2) 120+60=180, supplementary angles

3)

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.
