What's a circlet?

You mean circle?

Also Just to clarify 14 and 18 are length of line Inside the circle right?

@azure tinsel

[azure tinsel]

yes

sorry english is not my first language

[odd summit]

.

[azure tinsel]

yes

[odd summit]

K I will try

[azure tinsel]

tyyyy

[odd summit]

It's given that centre is within the lines right? It is in pen

[azure tinsel]

yes

the R is the radius

of the circle

and i try to solve it by trigonometry but i don t think that s the way (or it is but i can t see it)

[odd summit]

$$One thing i can see is
\sqrt{R^2 - 49} + \sqrt{R^2 - 81} = 8$$

😢 my latex so bad

[odd summit]

Why no space 😭

[azure tinsel]

is it the frmula of the circle?

[odd summit]

No

Wait I draw diagram

You do know that perpendicular from centre to chord divides it into 2 equal parts

@azure tinsel did you get?

[azure tinsel]

I ll draw better eait

Wait

[odd summit]

@azure tinsel I basically did x + y = 8

[odd summit]

No No need

[azure tinsel]

The 8 one isn t one cord

[odd summit]

It's the dist between chords right?

I found centre to chord dist thru Pythagoras for both chords and the summ of those should be 8

[odd summit]

Yes

[odd summit]

Look at this diagram

X + Y should be 8

Right?

@azure tinsel

[azure tinsel]

They r all like

Twist

[odd summit]

Wdym

[odd summit]

No No

This line should also be 8 right?

[azure tinsel]

Ok

[odd summit]

Yeah so now find x and y using Pythagoras

$$ x = \sqrt{R^2 - 49}$$

[dusk plover]

NoobExploded

[azure tinsel]

?

[odd summit]

No

Ignore the line on the left

[azure tinsel]

OHHHHH

I THINK I UNDERSTAND NOW

[azure tinsel]

Ok i ll try it

[odd summit]

$$ x = \sqrt{R^2 - 49}$$

[dusk plover]

NoobExploded

[azure tinsel]

Wait wait wait i ll try it xd

[odd summit]

K

[azure tinsel]

I ll let u know later xd

Thank u very much for your knowleage

[odd summit]

OK

Np

[quiet quest]

@azure tinsel

Did you get it?

Should be around ||267.04||

[quiet quest]

Don’t you mean 81?

[odd summit]

Yes

[azure tinsel]
