What is the ratio of interior and exterior angle of a regular polygon?
The ratio between exterior and interior angle of a regular polygon is 1:4.
What regular polygon has an interior angle of 9?
140 °
Excellent! So the interior angle of a 9 -sided polygon is 140 ° ….Solve the Question.
| Interior Angle of a Polygon | = | 180 ° · Number of Triangles Number of Vertices |
|---|---|---|
| | | |
| Interior Angle of a Polygon | = | 180 ° · 7 9 |
| | | |
| Interior Angle of a Polygon | = | 9 · 20 ° · 7 9 |
What is the exterior angle of a 9 sided polygon?
360°
A nonagon has 9 exterior angles. The sum of angles of the exterior angles of a nonagon is 360°.
How many sides does a regular polygon have if the ratio of an interior angle to its adjacent exterior angle is 7 2?
9
As sum of all exterior angles is 360∘ , total number of sides must be 360∘40∘=9 and polygon is nonagon. If it is not a regular polygon, 7:2 ratio must be between sum of all interior angles and sum of all interior angles. and n=7+2=9 and polygon is a nonagon.
What is the ratio of the interior angle to the exterior of a regular polygon with 6 sides?
Question 6 Q6) The ratio between the interior angle and the exterior angle of a regular polygon is 2 : 1.
What is the ratio of the interior angle to the exterior angle of a regular polygon with 5 sides?
Ratio of an interior and exterior angle of a regular polygon is 5:2 respectively.
How do you find the interior angle of an exterior angle?
All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides. The sum of exterior angles of a polygon is 360°.
Can the exterior angle of a regular polygon Measure 9 degrees?
Explanation: The exterior angles of any regular polygon must add up to 360o . Since the angle measure given iin the questions s 40o , take 360o40o = 9. Meaning there are 9 exterior angles and therefore 9 sides to the polygon.
What is the exterior angle of a polygon with 15 sides?
24
Exterior angle=24 for polygon of 15 sides.
How do you find the measure of each exterior angle?
The measure of each exterior angle of a regular polygon is given by; The measure of each exterior angle =360°/n, where n = number of sides of a polygon. One important property about a regular polygon’s exterior angles is that the sum of the measures of the exterior angles of a polygon is always 360°.
What is the ratio of an interior angle to the measure of an exterior angle in a regular pentagon?
How? Well the ratio of exterior to interior angle is 2:3 that is the angles are 72 and 108 degrees. Since the sum of the all exterior angles of any figure is 360 and if each angle is 72 degrees, then the figure must have 360/72 or 5 sides. Hence it is a pentagon.
What is the formula of exterior angles?
The sum of exterior angles of a polygon is 360°. The formula for calculating the size of an exterior angle is: exterior angle of a polygon = 360 ÷ number of sides.
What is the ratio of the interior angle of a polygon?
The ratio of an interior angle to the exterior angle of a regular polygon is 7 : 2 . Find the number of sides of the polygon. The ratio of an interior angle to the exterior angle of a regular polygon is 7:2. Find the number of sides of the polygon.
What is the ratio between the exterior angle and interior angle?
The ratio between the exterior angle and interior angle of a regular polygon is 2: 3. Each interior angle of a regular polygon = n180o(n−2) where n = number of sides of polygon Each exterior angle of a regular polygon = n360o
How do you find the interior angle of a nonagon?
Hence exterior angle is 20*2 = 40 degrees and the interior angle 20*7 = 140. The number of sides of the regular polygon = 360/40 or 9 sides. Check: A nonagon has 9 sides. Sum of the interior angles = (2n-4)*90 = (18–4)*90 = 14*90 = 1260 degrees. So each interior angle = 1260/9 = 140 degrees. Correct.
How many sides does a regular polygon have?
The total angle of a regular polygon is (n-2)180° where n is number of sides. Hence the interior angle is (n-2)180°/n. Also, the exterior angle is 180°-interior angle which is equal to 360°/n. By your data their ratio is 7:2. Hence, Hence that regular polygon has 9 sides. Thank you… Hope it helps… 8 clever moves when you have $1,000 in the bank.
