[Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | by calculating the exterior angle and dividing 360 by it.as the sum of exterior angles in a regular polygon equal 360 degrees. | True_Correct | null |
28,789 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | by working out what the exterior angle is you do 360 divided by it to find the answer | True_Neither | null |
28,790 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | calculate exterior angle then do it from there | True_Neither | null |
28,791 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | calculate the exterior then 360/(numb of ext) | True_Correct | null |
28,792 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | can be worked out be x angle. | True_Neither | null |
28,793 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | decagon
sum of interior angles = 1440
1440/10 = 144
it's a decagon which has 10 sides. | True_Correct | null |
28,794 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | decagon has 10 sides with an interior angle of 144*
triangle, 3 sides = 60* interior angle
144 divided by 60 = 2.4
144 x 10 = 1,440*, which is the interior angle sum of a decagon | True_Correct | null |
28,795 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | decagon has 10 sides. 144 * 10 = 1440, which is the amount of interior angles in a decagon. | True_Correct | null |
28,796 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | decagon sum of angles in 1440 | True_Correct | null |
28,797 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | decagons have the interior angle of 144 | True_Correct | null |
28,798 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | do not know how to explain it | True_Neither | null |
28,799 | 76,870 | This is part of a regular polygon. How many sides does it have? [Image: A diagram showing an obtuse angle labelled 144 degrees] | \( 10 \) | doing 10 x 144 and getting 1440. i knew this was the correct answer because to be a regular polygon, all angles must add up to an integer that is divisible by 90 and/or 9. 1440/9 = 160. | True_Correct | null |
