all angles will be equal to start we can use our handy dandy formula for the
total angle measure of a polygon
180 times N -2 with N being the number
sides a polygon to determine that the total angle measure
the figure is 180 times the quantity 12-2
This multiplies out to a whopping 1,800 degrees
all we have to do from here is divide the total angle measure
by that number of sides. We get 1800 divided by 12 which equals
150. So each angle measures a 150 degrees.
Answer choice A.
