Question 2

The ratio of the measures of an interior angle of a regular hexagon to that of a regular dodecagon is:

The internal angle of a hexagon(6 sides) = 120 degrees

The internal angle of a dodecagon(12 sides) = 150 degrees

Ratio of them = 120 : 150 = 4:5

Hence, option B is the correct answer.
