can anyone help me on this pic

Answer 1

@ZeHanz can you help me please

Answer 2

An interior angle of a heptagon can have ANY value between 0 and 360 degrees

Answer 3

17

Answer 4

hoped that helped you

Answer 5

@Jackie12345 no it got me confusesd

Answer 6

hah
its 128.57

Answer 7

@dazhaxia its one of the interior angles, not all of them

Answer 8

You know that the sum of the angles of a triangle is 180 degrees.
In a quadrangle, this is 360 degrees. It is as if a triangle has been "glued on" on of the sides of a triangle.
Every time you increase the number of vertexes, another 180 degrees is added.

3-angle: 180 deg
4: 360
5 540
6: 720 etc.

So the sum of the angles in a n-gon is (n-2)*180 degrees.
YOur regular heptagon has 7 vertices, so the sum of all its angles is 5*180=900 degrees.
Now, because is is regular, every angle is the same, so you can find out how many degrees each angle is.

Answer 9

ok sorry

Answer 10

yea so it have 7 angles so it have a total of 900 divided by 7=128.57?

Answer 11

Yes, that is how you do it...

Answer 12

@ZeHanz thank you you help alot! :)

Answer 13

YW!
