Question

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

Answer 1

135 degrees

Explanation:

Answer 2

Answer: 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
`(180(n - 2))/(n)`.

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
`(180(8 - 2))/(8)`.

Simplifying across the top, (8 - 2) is 6so we have
`(180(6))/(8)`.

180(6) is 1,080 so we have
`(1,080)/(8)` and

1,080 divided by 8 gives us 135.

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