Question

find the no of sides if each interior angle is 1 one fifth of a right angle​

Answer 1

Hey mate, here's your answer:-

Answer:

5

Step-by-step explanation:

1 whole 1/5 of 90° is 108°

We know that:

Side of a polygon= 360/exterior angle

Therefore, Exterior angle= 180° - Interior angle

=> 180° - 108° = 72°

So, Side= 360/72 = 5

Hope this helps! <3
