Use this pattern to predict the number of diagonals in a dodecagon (12-sided polygon). First create a triangle. Since you are looking for diagonals you must go from vertex to vertex, but they cannot be adjacent to each other. Therefore a triangle has no diagonals.

Answer:

The size of the scale model is 60 centimeters.

Step-by-step explanation:

Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:

1m = 100cm

10.8 m = (10.8 x 100) = 1080 cm

1080/18 = X

60 = X

Therefore, the size of the scale model is 60 centimeters.
