What is the measure of each interior angle of a regular octagon ?

135°

Step-by-step explanation: In this problem, we're asked to find the measure of  each interior angle of a regular octagon.

So let's use our formula for finding the measure of

each interior angle of a regular octagon which is .

In this formula, n represents the

number of sides of the polygon.

Remember that an octagon is a polygon that has 8 sides

so we plug a 8 in for n and we have .

Simplifying across the top, (8 - 2) is 6so we have .

180(6) is 1,080 so we have and

1,080 divided by 8 gives us 135.

So the measure of each interior angle of a regular octagon is 135°.
