You need to forward your ports right. I can't connect for mind to mind data transfer.

Oh well. Better luck next time.

When dealing with right triangles

Law of sines:

SinA/a = SinB/b = SinC/c

Low of cosine

a^2 = b^2 + c^2 - 2acCosA

Start with a triangle. What are the sizes of the angles and the individual lines between the angles? Can you inject artificial complexity into these observed sizes? Now make circles somehow relevant. There, you're done.

>>7708603
Put in identities and you are basically done.

Are you familiar with the Pythagorean theorem? It all stems from that.

Basically, magical shit happens when you inscribe a right triangle into a circle.

Sorry, law of cosine is actutally

a^2 = b^2 + c^2 - 2bcCos(A)

where a,b,c are lengths and A,B,C are their corresponding angles

Don't forget the two special triangles for quickly finding values.
π/4 triangle has opposite and agacent lengths of 1 and a hypotenuse of √2

π/3 triangle has opposite length of √3 adjacent length of 1 and hypotenuse of 2 and with an opposite angle of π/6.
Also remember that the only way you will really learn is by doing 100s of practice problems.
