Hi, its the GCSE brainlet from yesterday. Please can one of you

Cos(angle) = Adjacent/Hypotenuse
Hypotenuse(cos(angle)) = Hypotenuse(Adjacent/Hypotenuse)
Hypotenuse*cos(angle) = Adjacent
4*cos(50) = x

4 * cos50 = x

Thank you.

Why do you post here instead of /sqt/ ?
Neck you'reself brainlet

>>8474298
is the answer 3.85?

>>8474298
no wait its 2.57 sorry

>>8474286
Hehe. This puts me in a state of tranquility while thinking about the GCSE maths exams - weak opponents

*fuck off from /sci/, please*

>tranquility
Its ok i just want to get a 5, i hope your superior intelligence will fulfill your life man :)

>>8474335
These dudes on this board seem pretty cool about helping others with shitty questions

>GCSE Brainlet

Why are you on /sci/

Also, yes you are a fucking brainlet. I was studying the fourier transform at that point in my life.

[eqn]cos(50°) = \frac{x}{4}[/eqn]
[eqn]x = cos(50°) \cdot 4[/eqn]

Also, I don't mind helping anyone. I like maths, whether complicated or simple.

What the fuck is wrong with you? Read some books if you think 'tranquillity' is anything out of the norm

>>8474286
High school sophmore level math
Its just whatever cos(50) equals *4

What is a GCSE

>>8474649
General certificate of secondary education (piss easy, shouldn't require studying)

love how /sci/ is okay with shitposting 14 year olds. you guys should be ashamed.
