Question

Can someone help me with some Geometry questions, I don't have a lot of time to do this >.< please? (:

Answer 1

a) 8.57. you have a formula for this, it's = 360/ 42

Answer 2

c) 6300 . the same with b , just replace n =37

Answer 3

b) (n-2)180 /n = 171.43. sorry for my mistake

Answer 4

d) 92 since sum of interior of a pentagon is 540 . you can count it

Answer 5

e) 133 you have formula to count the sum of interior angle of a gon. you have hexagon, so the sum is = 720, substract other known angles, you have x = 133

Answer 6

wait can you show me how to do these?

Answer 7

do what?

Answer 8

like help me get the answer?

Answer 9

before you tell me the answer I mean

Answer 10

any answer have the argue how to get it, read it.

Answer 11

for question 1) central angle of a gon has formula is 360/n where n is number of sides of a gon, you have a 42-gon, it means you have 42 sides. just take n/42 . that's it

Answer 12

For #2 n now equals 37?

Answer 13

your #2 is a 42-gon, too. apply the same.

Answer 14

I give you the link of the website where I get the information, you read it. I try to help by reading it only, I am not good that much http://www.mathopenref.com/polygoncentralangle.html

Answer 15

about interior angles : here is the site http://www.mathsisfun.com/geometry/interior-angles-polygons.html

Answer 16

hope that help. about question #6. I know how to do it by myself. if you cannot, let me know then.

Answer 17

@jim_thompson5910 Could you help me please?

Answer 18

The sum of the central angles of a regular polygon is 360 degrees, so in a 42-gon each central angle will be 360/42=? degrees.

Answer 19

8.57

Answer 20

yep

Answer 21

Number 2?

Answer 22

This a quiz for a grade?

Answer 23

Or homework?

Answer 24

@karatechopper it does say quiz on the attachment. Take a look for ur self.

Answer 25

Well I see that, but I mean that sometimes people get quizzes for homework and we help em out..

Answer 26

yeah, true. But i truly dont know if its a quiz for a grade or homework.

Answer 27

Well since this one doesn't look like a true quiz that will put in as cheating, looks like a practice quiz, I'm gonna let it slide, continue helping along :)

Answer 28

okaii thanx @karatechopper

Answer 29

oh it is a online class though. if it helps at all.

Answer 30

Then the quiz would be in a url. Online school quizzes don't let you copy and paste

Answer 31

yeah they do, some of them give you an attachment (the quiz) and you do it, then turn it in.

Answer 32

I have an updated file of this now

Answer 33

@phi Any feedback?

Answer 34

for 6, you can use the idea that a straight line is 180 deg. use that to fill in the missing angles inside the hexagon

Answer 35

B is correct for #2

Answer 36

Is 6 D?

Answer 37

same idea for Q10. to fill in the exterior angle.

Answer 38

I think I'm doing something wrong why I'm not getting any of the answers :/

Answer 39

I don't remember. but the interior angle at F is 105 (because 105+75= 180)
at A it is 110
now you have the same problem as the earlier ones.

Answer 40

I still don't understand I'm sorry :/

Answer 41

In the figure for Q6, do you see the 75º right above F ?

Answer 42

Yes

Answer 43

Yes 6 is D
