Question

Please give me the answer of these questions

Answer 1

Let the exterior angle be 'a'

Interior angle = 3a

We know, interior angle+ exterior angle= 180

a+3a=180

4a=180

a=45°

Interior angle= 3a = 3 × 45= 135°

Exterior angle= 45°

Now ,

n×45=360

n= 360/4=8

n=8

Number of sides in the polygon is 8 sides
