Each angle of a regular octagon has a measure of degrees.

The measure of the interior angle of a regular octagon is 135°

Step-by-step explanation:

We have to tell the measure of each angle of a regular octagon.

As octagon has 8 sides and 8 angles.

The sum of interior angles of octagon are

Sum of interior angles=(n-2)180°

where n is the number of sides

Sum=(8-2)180°=6(180°)=1080°

As octagon is regular implies all interior angles are congruent.

So, the measure of the interior angle of a regular octagon is

Hence, the measure of the interior angle of a regular octagon is 135°

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
