How to calculate length of x?

>>

>>7633357

I'll give you a hint. A function is defined as the length of x (per your convention) in units of the radius of the circle, given an angle such as the one you marked as a parameter. The name of that function is cosine.

In other words, the cosine of the angle is the length of x in units of the radius (5 meters in your example).

Stupid questions belong in the stupid questions thread

>>

>>7633357

x/5 = cos(35)

x = 5cos(35)

x = 4.1

>>

>>7633383

you don't know the angle is in the centre of the circle

uncalculable

qed

>>

>>7633357

try using cosine you fucking retard. Unbelievable.

>>

>>7633412

180 - 35???

>>

i dont know if this helps

>>

>>7633481

what in the fuck

>>

>>

>>7633357

sin(35) = x/(x+5)

>>

I haven't seen the first answer

>>

>>7633535

Why would it not just be sin(35) = x/5 ?

is that line that's already drawn not equal to 5?

>>

>>7633357

this should be easy, hint: review your notes from freshman high-school

Is this /sci/ this fucking retarded?

DONE

prove me wrong faggot

prove me wrong camdyass

(x+5)sin35=x

x=6,73

>>

>>7633494

They have the right idea, they're just skipping the vital step where they change the angle from 35deg to 55deg. But either way works.

5sin(35deg)=5cos(55deg)=2.87

>>

>>7633620

it's a line from the center of the circle to the end of the circle. How is it NOT a radius?

>>

>>

>>7633623

but it's not a line from the center of the circle to the end of the circle

it stops too short

>>

>>7633633

Jesus Christ.

>>

>>7633357

If you're in high school I don't know what your "teacher" thinking giving this to you. Circular conic section analysis like this requires a year of linear algebra at least.

Oxford PhD. B.S. M.D. B.A. M.A. in every existing school of pure math, here. Trust me.

>>

>>7633648

x is not a radius, you moron.

>>

ITT: everyone types before thinking

>>

>>7633652

>x is not a radius

But it's measured from the center

>>

>>7633660

More like ITT Tech am I right?

Idiot

>>

>>7633663

Fucking retard.

>>

>>7633661

correct, but it's not measured directly to the perimeter

>>

>>7633357

you mathematicians make me laugh, science literally gave you guys rulers and calculators yet you guys continue to over complicate things

its literally one walrus man

>>7633481

It doesn't because no one can read what you wrote.

>>

>>7633741

Why are you touching his penor?

>>

>>7633357

is it 5 divided by 90 times by 35?

I dont do math btw

Please tell me you're joking.

lol wut

>>

>>7633744

is this /pol/ now? Can't a guy be figuresexual and not face discrimination?

>>

am i wrong here or can you just take the percentage the percentage that the 35 degree angle takes from 180 and mulitply that x5 to get the answer?

>>

>>7633748

No you fucking cluck, you could have touched his legs hands face chest. But you chose to harrass this poor walrus and touch his penor while he remained helpless. You sick bastard

good fucking god

This thread is giving me aids but also making me lul.

Imma solve to end this bullshit

>>

>>7633809

already solved faggot

also you didn't have to use cos(55), you could have just used sin(35)

x = 5*sin(35*pi/180)

why the fuck are you converting to radians?

Exact answers, please

x = 5sin(35) = 5(((-(6^(1/2))*(1+((3)^(1/2)/3)))/32 + i((-6(1+(3)^(1/2)/3)^2)+16)^(1/2)/32)^(1/3) + (-((6^(1/2))(1+3^(1/2)/3))/32 - i*((-6(1+(3^(1/2)/3))^2+16))^(1/2)/32)^(1/3))

kek

>>7633357

bro r u 12?

>>

>>7633357

X is adjacent to the angle, so use cosine.

[math]cos(35) = x/r[/math]

Therefore,

[math]x = r\times cos(35)[/math]

Obviously, [math]r[/math] is the radius.

>>

>>7638628

My bad, X is not adjacent. I'm legally blind.

Cos(90-35*)

>>7633357

Sin of angle=Opposite/hypotenuse

sin T=x/radius

radius*sin T=x

5sin(35°)

don't need a nuclear science degree to do this one kidos

>>

>>7633357

EVERYONE SHUT THE FUCK UP THIS IS THE CORRECT ANSWER.

cos(55)=(x)/(x+5)

x=(5/(1-cos(55)))-5

THERE IS NO DEBATE. IF YOU DISAGREE KILL YOURSELF

>>

YOU ARE A FUCKING RETARD

>>

Arccosine (7pi/36) for radians

Stop being a shitlord with degrees.

>>

>>7640668

its 5cos(35) u boob

>>7642598

whoops, sorry senpai it's actually sin. thought the 35 deg was from the horizontal axis

>>

>>7640717

>given degrees

>answers in radians

kill yourself

>>

Diagram is fucking retarded. Next time OP write the radius next to the line that actually extends

from the centre of the circle to the edge.

Originally thought the problem specified that the radius is x+5.

So here is the solution to that problem.

(x+5)*sin(35) = x

x = (5*sin(35)/(1-sin(35))

x = 6.725

>>

>>7642690

x>5?
