What is the amount of sides of a polygon with an interior angle of 176 degrees?

90 sides


What is the interior angle of a shape with 5 sides?

If it's a regular 5 sided shape, then 72o


What is the angle sum of a shape with 11 sides?

The formula to find the sum of the angles of any shape is: (sideCount-2)*180 If the shape has 11 sides the total interior angle is: 1620.


What is the number of sides when the interior angle is 180 degrees?

A shape has three sides if its interior angles add up to equal 180 degrees.


What is the interior angle for a perfect octagon?

To work out the angle of any 'perfect shape' you use this formula: interior angle =((number of sides - 2) x 180)/ number of sides for an octagon: interior angle =((8-2) x 180 )/ 8 = 135 degrees


What shape has 150 in each interior angle?

If the interior angle is 150° then the exterior angle measures 180 -150 = 30°. The sum of the exterior angles of a regular or convex polygon = 360° The number of sides is therefore 360/30 = 12 sides The shape is a dodecagon.


Do trapezoids have four interior angles?

Yes, they do. An interior angle is an angle inside a shape. A trapeziod (a quadrilateral with one pair of parallel sides) has four angles, all of them being interior.


One exterior angle of a regular polygon measures 30 what is the sum of the polygons exterior angle measures?

If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.


What is the interior angle of a 31 sided shape?

The formula for the sum of the interior angles of a shape with n sides is: 180 * (n - 2) So, for a 31 sided shape, the sum of the interior angles is 180 * 29 = 5,220.


What is the interior angle sum for a parallelagram?

360 degrees, same as any other shape with four sides.


How many sides does a regular polygon have if the measure of one interior angles is 144?

interior angle = (sides - 2) * 180 / sides sides * interior angle = 180 * sides - 360 sides * (interior angle - 180) = -360 sides = -360 / (interior angle - 180) sides = 360 / (180 - interior angle) So, for 144 degrees: sides = 360 / 36 = 10


How many side has a polygon got if the interior angle is 162 degrees?

Assuming every interior angle is the same, and they're all 162 degrees, the shape would have 20 sides.
