Question

Q13) Find the number of sides of a regular polygon whose each exterior angle has measure of 45°
Also find the measure of its each interior angle.
​

Answer 1

Answer: No. of sides= 8

Measure of each interior angle= 135°

Step-by-step explanation:

Please refer to the attachement to find the no. of sides..

To find the measure of each intterior angle we have to find the sum of all interior angle first---- (N-2)*180°

=(8-2)180

=6*180

=1080°  (Let it be 's')

Now, Each interior angle= s/n

1080/8  = 135°
