Question

if the measurment of each exterior angle of is 45°, then the number of sides in it is​

Answer 1

Answer:

8 sides i.e octagon

Step-by-step explanation:

exterior angle for a regular polygon, where n is the number of sides. So if we substitute the given angle in

$360 \div n = 45$

Ans..... n=8

Answer 2

Answer:

n=8°

Step-by-step explanation:

The sum of the exterior angles of a regular polygon = 360°

$45°×n=360°$ [each exterior angles is 45°]

$n=\frac{360}{45}$ [simplify]

$\huge\boxed{n=8}$

Therefore,

The number of sides of a regular polygon whose each exterior angle has a measure of 45° of 8..
