Hi, its the GCSE brainlet from yesterday. Please can one of you help me answer this question?

Hi, its the GCSE brainlet from yesterday. Please can one of you help me answer this question?

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

is the answer 3.85?

no wait its 2.57 sorry

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

*fuck off from Veeky Forums, please*

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

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

>GCSE Brainlet

Why are you on Veeky Forums

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

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

What is a GCSE

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

love how Veeky Forums is okay with shitposting 14 year olds. you guys should be ashamed.

Iwoniec

An exam you take in the UK when you're 16
