Question

HELP!!

Answer 1

cant really see it happening without more info; but then, I dont know it all :)

Answer 2

I was thinking that amistre.

Answer 3

theres prolly some ration geometry formula for it

Answer 4

^What i was thinking =) I don't know how to solve that lol

Answer 5

Like an angle or something?

Answer 6

the formula is 10^2=(21y)(y), i'm pretty suree...then you simplify it?

Answer 7

10^2=21y^2?

Answer 8

how'd you get that formula? did the question give it to you?

Answer 9

it's how you solve those kind of problems. i put the numbers in i just have to simplify it.

Answer 10

whats the formula to use?

Answer 11

10^2=(21y)(y)

Answer 12

10^2 = 20y i think

Answer 13

10^2 = (21+y)(y) right?

Answer 14

what grade are you in ?!?!

Answer 15

ummm..... the 35th grade if were counting lol

Answer 16

^^win

Answer 17

so you guys are old? that explains it

Answer 18

well, IM old lol

Answer 19

I'm 20 xP

Answer 20

haha oooookay..............

Answer 21

10^2 = (21+y)(y); i think this is the right formula, got it from a secant tangent sitse

Answer 22

YES! Secant tangent!!!

Answer 23

100 = 21y +y^2

y^2 +21y -100 = 0

Answer 24

I'm soooooo screwed..

Answer 25

-21/2 + sqrt(21^2 -4(-100))/2

Answer 26

therefore y^2+21y-100=0 solve as a quadratic y=-25 and y=4, however i guess since its a measurement u ignore the negative calue and only use 4

Answer 27

Forget this. Thanks for trying, guys. I love you even though you failed me <3

Answer 28

NICK I LOVE YOU.

Answer 29

4s good when I can count right lol

Answer 30

Forget this. Thanks for trying, guys. I love you even though you failed me <3

Answer 31

I'm soooooo screwed..

Answer 32

YES! Secant tangent!!!

Answer 33

so you guys are old? that explains it

Answer 34

what grade are you in ?!?!

Answer 35

10^2=(21y)(y)

Answer 36

it's how you solve those kind of problems. i put the numbers in i just have to simplify it.

Answer 37

the formula is 10^2=(21y)(y), i'm pretty suree...then you simplify it?

Answer 38

the formula is 10*10=y(21+y)
100=21y+y^2
y^2+21y-100=0

Answer 39

oh its upside down lol

Answer 40

\[y=\frac{-21 \pm \sqrt{21^2-4*1*(-100)}}{2} \]

Answer 41

\[y=\frac{-21 \pm \sqrt{841}}{2}\]

Answer 42

we will ignore the negative value since we are looking for a measurement

Answer 43

y=4
