Question

Find the measure of one interior angle in a octogon. Round to the nearest 10th if you need to.

Answer 1

An octagon is an eight-sided polygon. Therefore, an octagon has 8 sides.

To find the meassure of one interior angle, use the formula:

`(180(n-2))/(n)`

Where, number of sides, n = 8

Thus, we have:

`\begin{gathered} (180(8-2))/(8) \\ \\ =(180(6))/(8) \\ \\ =(1080)/(8)=135\degree \end{gathered}`

Therefore, the measure of one interior angle in an octagon is = 135 degrees

ANSWER:

135 degrees
