What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
What is the interior and exterior angles on a 20 sided shape?
Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
What are the interior angles of a 20 sided polygon?
If the 20-sided polygon is a regular polygon, then:The sum of all 20 angles = (20 - 2)180⁰ = 18(180⁰) = 3240⁰Each angle measure = 3240⁰/20 = 162⁰
How many degrees in a 20 sided shape?
The sum of the interior angles of an icosagon is 3240 degrees, each angle of a regular icosagon being 162 degrees. * The formula for the sum of an n-sided polygon is 180 (n-2). 180 x 18 = 3240
Interior angle of and 18 sided shape?
Exterior angle + interior angle = 180 Hence Interior Angle = 180 - Exterior Angle The Exterior Angle = n(No. of sides ) / 360 Substituting Interior Angle = 180 - (n/360) Interior Angle = 180 - (18/360) Interior Angle = 180 - (1/20) Interior Angle = 179.95 degrees.
What is the sum of the interior angle measures of a 20-sided polygon?
3240
What is sum of the interior angle measures of a 20 sided polygon?
3240
What is the size of an interior angle of a 20 sided regular polygon?
exterior angle = 360° ÷ 20 sides = 18° interior angle = 180° - exterior angle = 180° - 18° = 162°
What is the interior angle of a regular 23 sided polygon?
164o 20' 52.17''
What are the measurement of each interior angle of a icosagon?
Providing that it is a regular 20 sided icosagon the each interior angle measures 162 degrees
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
What is the sum of the interior angle measured by a 20-sided polygon?
162o. Method 1: Sum of interior angles of n-sided polygon = (2n - 4) right angles. In this case n = 20 so total of interior angles is 36 x 90o. Assuming polygon is regular then each interior angle is (36 x 90) divided by 20 = 3240/20 = 162. Method 2: Exterior angles of regular n-sided polygon = 360/n which in this case = 360/20 =18. Straight line is 180o so interior angle = (180 - exterior angle) = 180 - 18 = 162.
What is the exterior angle of an 18 sided shape?
The exterior angle of a 18 sided shape is 360/18 =20 degrees The exterior angle is always 360 divided by the numbe of sides of that polygon. =) what the hell im i doing answering this?
What is the interior and exterior angles on a 20 sided shape?
Interior angles total 40 - 4 right angles, ie 36 x 90o, so each interior angle is 18 x 9 ie 162o and the exterior is 180 - 162 = 18o
What is the measure of an angle of a regular 20-sided polygon?
The interior angles of an n-sided polygon add to (n-2)*180 degrees. So the interior angles of a 20-gon add to 18*180 = 3240 degrees. The 20-gon is regular so each angle is a 20th of this ie 3240/20 = 162 deg.
What are the interior angles of a 20 sided polygon?
If the 20-sided polygon is a regular polygon, then:The sum of all 20 angles = (20 - 2)180⁰ = 18(180⁰) = 3240⁰Each angle measure = 3240⁰/20 = 162⁰
