Question

How many degrees is one of the angles in a regular octagon?

Answer 1

135°

Explanation:

The sum of the interior angles of a polygon is

sum = 180° ( n - 2) ← n is the number of sides

Here n = 8 ( number of sides of an octagon ) , then

sum = 180° × 6 = 1080°

Then

size of 1 angle = 1080÷ 8 = 135°
