What is the size of the exterior angle of a 20 sided polygon?
The question can be answered only if the 20-gon is regular - ie all its angles are the same. IF that is the case, then: The sum of the exterior angles of any polygon is 360 degrees. Since there are 20 exterior angles, each of them must be 360/20 = 18 degrees.
What is the measure of a vertex angle of an isosceles triangle if the measure of an exterior at the base is 100 degrees?
20 degrees and the two equal angles will be 80 degrees each
What type of triangle has an angle that measures 20 degrees and and angle that measures 90 degrees?
Any triangle that has an angle measuring 90 degrees is a right triangle.
What is the supplamentary angle of 160 degrees?
20 degrees. the definition of a supplementary angle is two angles that add up to 180 degrees.
What complementary angle to a 70 degrees angle has a measure of?
Complementary angles add to 90 degrees so the complementary angle to 70 degrees has a measure of 20 deg.
What is the exterior angle of an 20 sided shape?
If it's regular then 360/20 = 18 degrees
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 measure of the interior angle and the exterior angle of a regular polygon with 20 sides?
Each exterior angle measures 20 degrees Each interior angle measures 160 degrees
What is the measure of an interior angle with an exterior angle o 20 degrees?
It is: 160 degrees
What is the exterior angle of a regular 20 sided angle?
18 degrees
What is the measure of each exterior angle of a 20 gon?
If it is a regular polygon then each exterior angle is 360/20 = 18 degrees
What is the exterior and interior angles of a regular 20-gon?
Exterior angle measures 18 degrees Interior angle measures 162 degrees
The exterior angle of a base angle in an isosceles triangle is 100 degrees What is the measure of the vertex angle?
20 degrees
What is the measure of an angle in a regular 18-gon?
Exterior angle = 20 degrees Interior angle = 160 degrees
Measures of an exterior angle of 20-gon?
Providing that it is a regular 20-gon then each exterior angle is 360/20 = 18 degrees
What is the exterior angle sum of a 20-gon?
The sum of the exterior angles of any (closed) shape will always be 360 degrees. The exterior angles of any polygon always add up to 360 degrees * * * * * The second of the above two answers is more accurate. A closed shape can be a circle, which does not have exterior angles.
Interior angle for 20 sided shape?
Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
