Final answer:
The number of diagonals in a 6-sided figure is 9.
Step-by-step explanation:
The formula for finding the number of diagonals in an n-sided figure is 1/2(n² - 3n). We can use this formula to find the number of diagonals for a 6-sided figure.
Substituting n = 6 into the formula, we get:
Diagonals = 1/2(6² - 3*6)
Simplifying,
Diagonals = 1/2(36 - 18)
Diagonals = 1/2(18)
Diagonals = 9
Therefore, a 6-sided figure has 9 diagonals.
