Answer:
7
Step-by-step explanation:
number of diagonals in a regular polygon = number of sides - 2.
A nonagon is a polygon having 9 sides.
Total number of diagonals in a regular nonagon
= 9 - 2
= 7
The bigger number is 42 and the smaller number is 10
The first equation tells you that . If you substitute this expression for in the second, we have
And we can deduce
