Suppose one angle is x and the other angle is 14x. Supplementary angles add to 180o, so x+14x = 180 15x = 180 x = 180/15 x = 12. The required angle is 12o. Check: The second angle will be 14*12 = 168. 168+12 = 180, so the large angle is the supplement of the small one.

Measuring from the minute hand (at 12) and going clockwise, it would be 210 degrees.
At 12:30 the hour hand would be halfway between 12 and 1. So on the right hand side there would be an obtuse angle (165 degreees) whereas on the left there would be a reflex angle (195 degrees).

Since the sum of measures of the two supplementary angles is 180⁰, we have:180⁰ - 165⁰12' = 179⁰60' - 165⁰12' = (179 - 165)⁰(60 - 12)' = 14⁰48'
Supplementary angles add up to 180 degrees You can solve for the supplementary angle first. You can solve for the other directly, but the math is a little more involved. Let A be an angle Start with the supplementary angle. A + ??? = 180 The angle you want is 12 less than twice as big A + (2A - 12) = 180 Solve for A: 3A - 12 = 180 3A = 192 A = 64 Remember A is the supplementary angle, so subtract the angle we solved for (A) from 180 to find the angle you want. 180 - 64 = 116
About 12 13 kernels if 1 cup measuring cup can hold 165 dried corn kernels.
Suppose one angle is x and the other angle is 14x. Supplementary angles add to 180o, so x+14x = 180 15x = 180 x = 180/15 x = 12. The required angle is 12o. Check: The second angle will be 14*12 = 168. 168+12 = 180, so the large angle is the supplement of the small one.
Yes and it will have 12 equal interior angles of 150 degrees and 12 sides
It is a 12-sided polygon, a dodecagon.The exterior angle for a polygon of n sides is 360/n.Each of the interior angles are supplementary angles (180-exterior angle).(180-150) n = 36030n = 360n = 12

No: The sum of the exterior angles of a polygon is 360o. For a dodecagon (12 sides) the exterior angle is 360o / 12 = 30o. The interior and exterior angles are supplementary and so they sum to 180o; thus the interior angle of a dodecagon is 180o - 30o = 150o. For an interior angle of 144o, the exterior angle is 180o - 144o = 36o, so there are 360o / 36o = 10 sides (a decagon).
At 12:30 the hour hand would be halfway between 12 and 1. So on the right hand side there would be an obtuse angle (165 degreees) whereas on the left there would be a reflex angle (195 degrees).

AnswerIt is Dodecagon.To find this, you have to first find the exterior angle of the polygon. Since the exterior angle of a polygon is always supplementary to the interior angle, you subtract the measure of the interior angle from 180. 180-150=30. Now You divide 360 by the measure of the exterior angle to get the number of sides of the polygon. 360/30=12. A 12-sided polygon is called a dodecagon
