Can anybody help me on this math question for number 3 and Find the measure of each interior angle of the regular polygon?

the measure of each angle is 150.

Step-by-step explanation:

in order to find this you need to find the measure all the degrees which can be found with (n-2)x180

in this case this is (12-2) x 180

so you would get the total degrees in the inside is 1,800

then there are a total of 12 interior angles so divide 1,800 by 12 to get 150 for each interior angle (btw this is only possible since this is a regular polygon meaning that every one of the angles are the same )

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
