Answer 2

Answer:

• Given:
• Number of diagonals of a polygon = 20
• To find:
• The number of sides of the polygon
• Calculation:
• The number of diagonals of a polygon having n sides is given by the formula
• Number of diagonals = n(n-3)/2
• By substituting the given data in the above
• formula
• => Number of diagonals = n(n-3)/2
• => 20 = n(n-3)/2 => 40 = n²-3n
• => n²-3n-40 = 0
• => n²-8n+5n-40 = 0
• => n(n-8)+5(n-8) = 0
• => (n-8)(n+5) = 0
• As n cannot be negative
• => n-8 = 0
• => n = 8
• 7
• The number of sides of the polygon are 8
