Answer:
The answer is
Step-by-step explanation:
1) Let no of sides of regular polygon be n
Each interior angle = 160°
Each interior angle = 160°
(2n -4) x 90° /n = 160°
180n - 360° = 160n
n = 360° /20 = 18
2) Let no of sides of regular polygon be n
Each interior angle = 135°
(2n -4) x 90° /n = 135°
180n - 360° = 135n
n = 360° /45 = 8
3) No. of sides = n
Each interior angle = 1.1/5 right angles
= 6/5 × 90
= 108°
∴ (n – 2)/n × 180° = 108°
180n – 360° = 108n
180n – 108n = 360°
72n = 360°
n = 5
