Please help. General math thread is not found.
a, b and betta are given. Find alfa!
Simple expression is needed.

i think you can use the law of cosines..?
Do you know how to solve it? I need your mind power, dear scientist!
Let the third angle be gamma. Then a/sin beta = b/sin gamma. From this it is easy to solve for gamma. Then alpha is 180 degrees - beta -gamma.

Complete expression is needed.
Are theese steps right?
Pi - /alpha - /beta = arcsin(b sin(/beta) : a)
/alpha = -Pi + /beta +arcsin(b sin(/beta) : a)
Could you help me?
Please.

Jesus christ i learned this in middle school you fucking autist
Google law of cosines
a/sin(beta)=b/sin(gamma)
solve for gamma
alpha=180-beta-gamma

Are you kiddin me?
Full expression, not this bullshit about sin-cosine theorems. Excplicit formulae is needed, not that BULLSHIT.
>>7722629
cosine law IS an explicit fucking formulae
c^2 = a^2 + b^2 − 2ab cos(C)
you just need to use sine law first to find side c so you can use it with cosine law, and if you need an explicit formulae for sine law then you're a fucking lost cause anyway.
I'd suggest to stop all attempts to assist this imbecile.
