(360) / (180 - n) n= interior angle in this case it will work like this: 360/(180-120) 360/(60) 6, so the number of sides is six.

What is the interior angle of a pentagon?
The measurement of an interior angle of a pentagon depends on whether the pentagon is a "regular pentagon". The sum of the measures of the interior angles of any polygon can be calculated using the formula (n-2)180, where n = the number of sides. If the pentagon is a regular pentagon, then all of the interior angles are congruent (i.e. : 144 degrees). Interior angle is the inside angle of any angular object. A triangle for instance has three outside angles and three interior angles, the angles of the points from the inside.
How do you solve for the interior angle using only the exterior angle?
a circle is 360 degrees. so whatever exterior angle u have u can subtract it from 360 to see what the interior angle is!
If an interior angle of a regular polygon is 168 degrees what is the name of the polygon?
It is a triacontagon, or 30-sided shape.The formula for one interior angle of a regular n-sided polygon is 180(n-2)/nwhere 180 (28) / 30 = 168*You can QUICKLY and EASILY find the answer using the formula for one exterior angle : it is 360/n360/30 = 12 and the interior angle is 180-12 = 168.The algebraic equation is(180-168) n = 360
What angle measure is a kite?
I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles. The "kite" is a quadrilateral whose four corners have angles of 72, 72, 72, and 144 degrees. The "dart" is a non-convex quadrilateral whose four interior angles are 36, 72, 36, and 216 degrees. If however if the questioner want to determine an unknown angle in of a general kite quadrilateral (two sides of length a and two sides of length b, not a parallelogram) when the length of all sides and one angle is known, then the equation [which is too complex for me to easily transcribe] can be found in the Geometry Atlas http://www.geometryatlas.com/entries/153 I can answer this if the question concerns Penrose tiling using "kite" and "dart" tiles.

What is the sum of the interior angles of a polygon with 33 sides?
Sum of interior angles of any polygon is 180 degrees.Another Answer:-The interior angles of a polygon with 33 sides add up to 5580 degrees using the formula (33-2)*180 = 5580
How do you find the amount of sides of a shape using it's interior angle?
for a polygon you use order of operations with this equation: [# of side subtracted by 2] multiply by 180= your answer
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
What is the interior and exterior angle for a regular decagon?
A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.
What is the sum of an interier angle of and octagen?
The sum of all the interior angles of any octagon is 1080 degrees, so that means that each angle is 135 degrees. You can find the measure of all the interior angles of any ploygon by using this equation: (number of sides in the polygon subtracted by 2) all multiplied by 180.
How many sides does a regular polygon have if each angle measures 144 degrees?
We have the interior angle 144∘ . We can find the number of sides using the formula as follows. Thus, the polygon has 10 angles and 10 sides.
How many sides does a polygon have when the measure of each interior angle is 144?
A regular polygon with interior angles of 144 degrees has 10 sides. Using the fact that a regular n-gon has interior angles of degree (n-2)*180/n, you can solve for the number of sides fairly easily.
What are the 3 trig ratios and how do they work?
A right angle triangle has three sides and three interior angles one of which is 90 degrees. The names of its sides are the adjacent the opposite and the hypotenuse and using the 3 trig ratios we can find the interior angles or lengths of the sides depending on the information given.Tangent angle = opposite/adjacentSine angle = opposite/hypotenuseCosine angle = adjacent/hypotenuseIf we are given the lengths of 2 sides we can work out the angles with the above ratios.If we are given a length and an angle we can work out the lengths of the other 2 sides by rearranging the above ratios.
What is the angle measure for each interior angle of a pentakaidecagon?
A pentakaidecagon (or pentadecagon) is a 15-sided figure, using the theorem:[180 x (n-2)]/n to find the angle measurement of each angle (where n is the number of sides) we get 156 degrees.
What is the formula used to calculate the number of sides in a polygon using its angle measures?
Let S be the sum of the measures of all the interior angles, in degrees. Then the number of sides is S/180 + 2.

Do you have to measure the sides while measuring an angle?
When measuring an angle you have to measure the sides using a protractor.
Can the measure of interior angle of a regular polygon can be found using 2 n-4 x 9 if n equals number of sides?
The formula is normally: (n-2)*180 = sum of interior angles whereas 'n' is the number of sides of the polygon
