I need number 7 and 9 please show work if you can

. sum of interior angles:

Heptagon: 900°

14gon 2160°

Step-by-step explanation: Divide 360 by the number of sides to get the measure of the average or regular central angle (same as an exterior angle)

360/7 = 51.43 360/14 = 25.7.

Subtract from 180 to find the interior angle.

180 - 51.43 = 128.57

180 - 25.7 = 154.3

Multiply the measure of the interior angle by the number of sides to find the sum of the interior angles.

128.57× 7 = 900

154.3 × 14 = 2160

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.

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.
