Answer 1

Sketch the polygon described. If no such polygon exists, write "not possible".

A regular polygon, one of whose angles has measure of 130.


I believe it is \(\bf\color{red}{not~possible}\).

Answer 2

yes that is right

Answer 3

hmmm what makes you think is not possible?

Answer 4

Because the interior measure cannot exceed 180, right?

Answer 5

btw... .it doesn't say if it's an internal or external angle
we're assuming is an internal angle I gather, but it really doesn't say

Answer 6

And I suppose so too, but the interior cannot have a measure greater that 108. right?

Answer 7

hmmm you mean the SUM of interior angles in a TRIANGLE, yes... they sum up to 180
but that's just a triangle, which can be a regular polygon of 3 angles

Answer 8

Oh .-.

Answer 9

well i thin interior angle can have measure greater than 108
yes they can

Answer 10

welll.... taking an assumption is an internal angle it's referring to
sum of all internal angles in a polygon sum up to

sides * angle = 180( sides - 2)

so.... say we know the internal angles are 130 so
angle = 130
sides = n

n * 130 = 180( n -2) <---- if you solve for "n" to see how many sides it's.... what does it give you?

Answer 11

I have no idea

Answer 12

if it were an external angle
sum of all external angles sum up to 360 or

sides * angle = 360
angle = 130
sides = n

n * 130 = 360 <---- solving for "n"... how many sides does it have?

Answer 13

well... is just a plain linear simplification.. surely you've covered that already, or you've been expected to

Answer 14

No, I have no idea what that is. .-.
I know the formula to find how many sides, and I was alright at it, but now it confuses me.

Answer 15

well... to find the angles... is the same as to get the sum of all angles really
the equation can get either

Answer 16

to find the sides rather...is the same equation as the sum of all angles....
the ones above ^

Answer 17

Okay, so would I take 180-130 then take that number and divide 130 by it to find the number of sides?

Answer 18

to find the sides assuming is 130 internal angle?

sides * angle = 180( sides - 2)

so.... say we know the internal angles are 130 so
angle = 130
sides = n

n * 130 = 180( n -2) <---- if you solve for "n" to see how many sides it's.... what does it give you?

Answer 19

Yeah, I know the formula, but I don't know how to get rid of the n's and still get a correct answer.
Meaning I don't remember how to solve the algebra. .-.

Answer 20

hmm you may want to brush up your linear simplification first then

Answer 21

Okay, but how? o.O

Answer 22

(And sorry, I know I'm a lot of work. I have a terrible memory when it comes to math stuff.)

Answer 23

Help? @sleepyjess .-.
