Question

The sum of angles of an octagon is ______.

120°
1080°
450°
180°

hint Hint:

Interior angle = (n-2) $\times$ 180 $\circ$ (Octagon has 8 sides)

The correct answer is: 1080°

option B is the correct answer
1080°

sum of all Interior angle = (n-2) $\times$ 180 $^{\circ}$
Where n is the number of sides in a polygon.
Interior angle = (n-2) $\times$ 180 $^{\circ}$ (Octagon has 8 sides)
= 6 $\times$ 180 $^{\circ}$ = 1080 $^{\circ}$
