Question

The number of diagonals of an n sided figure is 1/2(n²-3n). Use the formula to find the number of diagonals for 6 sided figure​

Answer 1

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.
