zinc vine Dec 28, 2023, 1:05 PM

#

Sure

lament depot Dec 28, 2023, 1:06 PM

#

ok

#

do u kno the angle of OBA and OCA

zinc vine Dec 28, 2023, 1:07 PM

#

It was not given but its probably 90 bc of the radius

lament depot Dec 28, 2023, 1:07 PM

#

YES

#

then wuts the angle of BOC

zinc vine Dec 28, 2023, 1:08 PM

#

120

lament depot Dec 28, 2023, 1:08 PM

#

yes

#

btw is the length of AB given?

zinc vine Dec 28, 2023, 1:09 PM

#

Ab and ac is equal

#

But not given

lament depot Dec 28, 2023, 1:09 PM

#

where di u get this problem

zinc vine Dec 28, 2023, 1:10 PM

#

#

11th question

lament depot Dec 28, 2023, 1:12 PM

#

wuts the 10 above segment AB

#

isnt that the length

zinc vine Dec 28, 2023, 1:13 PM

#

Yw

#

Ye

lament depot Dec 28, 2023, 1:13 PM

#

ok

#

so u connected point O to A

#

so in triangle ABO

#

lets say ∠AOB=θ

#

then how much is θ

zinc vine Dec 28, 2023, 1:16 PM

#

0

lament depot Dec 28, 2023, 1:16 PM

#

?

zinc vine Dec 28, 2023, 1:17 PM

#

Oh

#

Wait

lament depot Dec 28, 2023, 1:17 PM

#

θ is a symbol for angle

zinc vine Dec 28, 2023, 1:17 PM

#

How can it be equal to Ò

lament depot Dec 28, 2023, 1:17 PM

#

its a greek letter

zinc vine Dec 28, 2023, 1:17 PM

#

Oh

lament depot Dec 28, 2023, 1:18 PM

#

so wuts θ

zinc vine Dec 28, 2023, 1:18 PM

#

60?

lament depot Dec 28, 2023, 1:18 PM

#

YES

#

then

zinc vine Dec 28, 2023, 1:18 PM

#

So the sides are qual

#

R is 10

lament depot Dec 28, 2023, 1:19 PM

#

no no no

#

$tan \theta = \frac{AB}{OB}$

R4f43l1006

zinc vine Dec 28, 2023, 1:20 PM

#

Oh

#

Ye i know this

lament depot Dec 28, 2023, 1:20 PM

#

OB is the radius

#

right?

zinc vine Dec 28, 2023, 1:21 PM

#

Ye

lament depot Dec 28, 2023, 1:21 PM

#

then the answer is?

zinc vine Dec 28, 2023, 1:22 PM

#

How much is tan120

#

?

lament depot Dec 28, 2023, 1:23 PM

#

no θ =AOB

zinc vine Dec 28, 2023, 1:23 PM

#

Right

lament depot Dec 28, 2023, 1:23 PM

#

how much is AOB

zinc vine Dec 28, 2023, 1:23 PM

#

So squareroot of 3

lament depot Dec 28, 2023, 1:24 PM

#

yes tanθ=√3

zinc vine Dec 28, 2023, 1:25 PM

#

I got the answer

lament depot Dec 28, 2023, 1:30 PM

#

@zinc vine heres an shorter way
