Correct Answer - Option 3 : 560
Given:
Number of sides in the polygon = 35
Formula used:
Number of diagonal in the polygon = n(n – 3)/2
Where,
n → Number of sides in the polygon
Calculations:
Number of diagonal in the polygon = n(n – 3)/2
⇒ 35 × (35 – 3)/2
⇒ 35 × 16 = 560
∴ The number of diagonal in a 35 sided polygon is 560
