The angle opposite side RT = 12 will have the smallest measure
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
116 degrees
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.
Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
Let the measure of the angle be ( x ) degrees. Its complement is ( 90 - x ) degrees. According to the problem, ( x = (90 - x) - 12 ). Solving for ( x ), we get ( 2x = 102 ), leading to ( x = 51 ) degrees. Therefore, the measure of the smaller angle is 51 degrees.
It is angle RST.
The smallest internal angle possible for a regular polygon is 60 degrees. So either the angle is not 12 degrees or it is not an internal angle.
116 degrees
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.
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.
78
90-78 = 12 degrees
Providing that it is a regular polygon then each exterior angle will measure 12 degrees
0 degrees
This is what is called basic geometry, usually for 8th or 9th graders. When one is this age, there will be a text book that explains these things. I suggest you..look..it...up.
Exterior angle: 360/12 = 30 degrees Interior angle: 180-30 = 150 degrees
For the 12-sided polygon, each exterior angle is 30 degrees (360/12).
