all angles will be equal to start we can use our handy dandy formula for the
- 00:24
total angle measure of a polygon
- 00:26
180 times N -2 with N being the number
- 00:31
sides a polygon to determine that the total angle measure
- 00:34
the figure is 180 times the quantity 12-2
- 00:38
This multiplies out to a whopping 1,800 degrees
- 00:43
all we have to do from here is divide the total angle measure
- 00:46
by that number of sides. We get 1800 divided by 12 which equals
- 00:51
150. So each angle measures a 150 degrees.

Answer choice A.
