The number of diagonals (a) that can be drawn in polygons with a given number of sides (n) is being investigated
a
(a) 12
(d) 19.
Number of sides (n)
3 14 15 16 17 8
Number of diagonals (d) 0 2519
b
On the basis of the above information, answer the following questions :
(1) By considering the pattern, the value of 'a' is :
(b) 14
(c) 16
(ii) By considering the pattern, the value of 'q' is :
(a) 16
(b) 19
(c) 20
(d) 22.
For a polygon, d and n are related as d= An? + 3n.
(i) The relations between 'd' and 'n' for a quadrilas oral and a hexegon are
(2) SA + 2B = 1; 12A + 2B = 3
(5) 94 + 3B = 0; 5A + 2B = 2
(d) 3A + 4B = 0; 8A + 5B = 3.
(iv) Solving the two equations of (iii), the correct values of A and B are :
