Question

Find the number of sides of a regular polygon if each of its exterior angle is 45 degrees.
What is the sum of interior angles of an octagon

Answer 1

Answer:

exterior angle = 45°

= 360/45°

= 8

So first will have eight sides or octagon.

sum of Interior angles of octagon = ( n - 2 ) × 180° ,

where 'n' is the number of sides.

= ( 8 - 2 ) × 180°

= 6 × 180°

= 1080 °
