Number of sides in a polygon

All but one of the interior angles of a convex polygon measure 163. How many sides could the polygon have?

 

Please help me understand this. Thanks.

All of the interiour angles must add up to 180 degrees, so 3. The side can't be more than 180 by definition, and polygons are measured in 180s.
answered Mar 3, 2011 by anonymous
This statement is not true.  They add up to multiples of 180...
yeah what they said or he/she said

which of these shapes is a four sided figure with only one pair of parellel sides?

1) trapezoid

2) rectangle

3) square

4) rhombus
answered Jan 31, 2012 by anonymous
This is a new question. You can ask it from http://mathhomeworkanswers.org/ask to get more help.
A trapezoid because it only has 1 set of parallel lines and it's 4 sided. The other 2 lines are intersecting lines. I hope it helps.
A Rectangle is a more likely 4 sides and have parellel sides and top and bottom.

あなたはばかです。あなたはセツイーです。

The formula to find the interior angles a polygon is (n-2)180 = measure of an angle.

(n-2) 180 = 163

n-2 = 180/163

n-2 = .905

n = 3

 

The answer is three!

it is a trapezoid. pretty easy if you ask me.
answered Mar 13, 2012 by anonymous

[(n-2)x180]/n=interior angle measure of any regular polygon

Above is the formula for finding the number of sides to a regular polygon. Because what you describe is not a regular polygon, an irregular, it is impossible to decipher what the amount of sides, therefore you have given everybody a trick question to answer. This leaves all answers before this null and void with inaccurate result. Also waltjhall has the wrong formula and obviously does not realize that you can never have a decimal in the number that n is equal to.

Well i have a question....how many sides does a pentagonal prism have?
answered Apr 10, 2012 by anonymous
a prism is a solid or three-dimensional figure... so it has either edges or faces...not sides...
Four exterior angles of a pentagon measure 20°, 81°, 33°, and 152°. What is the measure of the of the fifth exterior angle?
answered Apr 30, 2012 by anonymous
as many as you want

(n-2)180/2 the formula of interior angle of a polygon.
answered Aug 28, 2012 by anonymous
NO!!!... i DON'T agree with you... to get the measure of an interior angle of a regular polygon = (n-2)180 / n
EXAMPLE:   the   n =  3  which is a triangle
                 (3-2)180 / 3  =  180 / 3  =  60 degrees is the measure       of each 3 angles of the triangle

how bout regular polygon...evree angel the save

then senter angel=360/n...n=number sides

outside angel=senter angel, so inside angel=180-outside=180-senter angel

angel=180 -(360/n) & yu want it tu be 163 deg

180-163=17=360/n

so n=360/17=21.176

regular polygon with 21 sides hav senter angel=17.142857 & inside angel=263.86725

or tri 20 sides: inside=180-18=162 deg

not a parallelagram or a rectangle of any type but a pentagon has 2 right angles and only 1 pair of parallel sides so if you look it over the pentagon is the correct answer
answered Apr 21 by Maddy
Draw and name the figure that has only one pair of parallel sides and exactly two right angles.
