get yourself a cartesian circle, or just look at one online and translate it from there 3,6,9, and 12 would all be 90 deg increments.
When it is 7:00, the hour hand and minute hand of a 12-hour clock form a 150° angle.

If the interior angles add up to 1800 degrees then it is a 12 sided polygon.
The measure of the angle in degrees 1 12 can be interpreted as 1 degree and 12 minutes. Since there are 60 minutes in a degree, 12 minutes is equal to 12/60 = 0.2 degrees. Therefore, the total measure of the angle is 1 + 0.2 = 1.2 degrees.
The angle opposite side RT = 12 will have the smallest measure
180 degrees( 12-2)=1800degrees This is the sum of the interior angles. So divide 1800 by 12 and have the measure of each angle.

90-78 = 12 degrees
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
