Question

This picture of a rectangle drawn around a regular octogan Find the value of x

60
45
55
67.5

Answer 1

Explanation:

the sum of all exterior angles of any polygon is 360°.

therefore, the formula for calculating the size of an exterior angle of a regular polygon (all sides are equal) is: 360 / number of sides.

x = external angle

an octagon has 8 sides.

so,

x = 360/8 = 45°
