Question

The figure shows two congruent regular polygons.

What is the value of m?

100

80

72

90

Answer 1

help pleaseee

Answer 2

so there are poligons with 9 sides ,yes ?

Answer 3

yes 9 sides

Answer 4

so can you calcule it how many degree will be the angle what is formed from two sides ?

Answer 5

so if this is difficile hence so can you tel me one poligon will be formed from how many the same triangles ?

Answer 6

with 2 angles i think it would be obtuse , but i dont know how to get the degree's

Answer 7

im sorry i dont understand :/

Answer 8

ok look please if there are nine sides equales so this signe that this poligon we can separated in 9 equales triangles

yes

ok ?

Answer 9

so from this you can calcule easy how many degrees will be one centrale degree of a triangle ,yes ?

Answer 10

and how would you find the central degrees ? 9 equal triangles .. do you add them together or something ?

Answer 11

so you know that the circle has an central angle of 360 degree

yes ?

Answer 12

so than you need just divide this 360

Answer 13

by 9

Answer 14

oo okay yes 360 that makes sence , so 360 / 9 ?

Answer 15

thats 40 ? so what would i do after i get 40

Answer 16

do i add 40+40 ?

Answer 17

sorry my internet conection is wrong slowly

Answer 18

so no

after you g

Answer 19

afte

Answer 20

afte

Answer 21

et after you get that the central degree of a triangle equal 4 degree so than you can easy calcule how many degrees will be the second and 3-rd angles of this triangle

Answer 22

40 degrees

sorry

Answer 23

its okay , wont they all be 40 though ?

Answer 24

why ?

Answer 25

the sum of the angles of a triangle how many is ?

Answer 26

hope so much that you know it ?

Answer 27

180 degrees

yes ?

Answer 28

sum of a triangle is 180

Answer 29

yeah

Answer 30

so than if you know that the central angle has an angle of 40 degree so than the second and 3-rd angle will be how many degree

Answer 31

70 ?

Answer 32

yes right

Answer 33

so if you know this so than the angle what is formed from two sides of poligon how many degrees will have

Answer 34

72 O.o ?

Answer 35

moment please
