Question

Help please...

Answer 1

B

Answer 2

what I did was to find first the angle that is suplementary to 85 which gives me 95 because thats a semicircle and O is the diameter.So after you get that the angle of 95 the arc that is infront of 95 is arc BC.Arc is twice the angle which means that if the angle is 95 it would be 95*2=190 then you got the arc BC.Now try to find angle A the arc that is on infront of angle A is the same BC so like I said if 190 was arc BC how much you think will it be the angle A?.

Answer 3

okay thank you!! :) can you help me with a couple more?

Answer 4

I'll try my best

Answer 5

ok :}

Answer 6

I think it's A I don't know a explanation and can't remember too much about it but if you really think about it A is the one that mostly doesn't make any sense.

Answer 7

mm ok

Answer 8

I think its B since the angle is congruent then the arc are congruent too.

Answer 9

ohh i thought it was C

Answer 10

@joshhfers

Answer 11

I'm sorry lol I put the wrong one haha :3 yeah its C sorry my mistake

Answer 12

lol its fine :) i

Answer 13

let me get a paper I think I have a formula for this

Answer 14

ok

Answer 15

I'm trying to use the formula angle/360*circumference

Answer 16

oh okay :p

Answer 17

but it keeps me giving 28.26 lol

Answer 18

lol D:

Answer 19

AB = 2 * BC = 2 * sqrt(155) = 2 * 12.45 = 24.9

Answer 20

i got ^^

Answer 21

nicee :) I didn't think about

Answer 22

where you got the 155 from?

Answer 23

BC^2 = BO^2 - CO^2
BC^2 = 18^2 - 13^2
BC^2 = 31 * 5
BC^2 = 155
BC = sqrt(155) =

Answer 24

nicee! good job! :D

Answer 25

thanx :DD

Answer 26

C

Answer 27

the formula for this is (x-h)square 2+(y-k)square 2=radius square 2

Answer 28

okay ty :)

Answer 29

im sorry not that question ^^ its C i already did that one..

Answer 30

oh okay

Answer 31

how did you do it?

Answer 32

not on this question I mean before this one

Answer 33

oh i did it yesterday, i dont remember

Answer 34

lol okay

Answer 35

yeah haha

Answer 36

I don't get this one I just think its D

Answer 37

I think it's B because the properties of a rhombus. Opposites angles are congruent and corresponding angles are supplementary I guess

Answer 38

so its B

Answer 39

mm yeah

Answer 40

okay thank you ! :)

Answer 41

welcome :) talk to me when you need more help

Answer 42

okay! :)

Answer 43

i will message me
