(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Completely solve this triangle. No calculators please.

A=?

B=Pi/3

C=?

a=(1+sqrt(3))

b=?

c=2

2. Relevant equations

Cosine law: b^2=a^2c^2-2ac(cos(B))

Sine law: Sin(A)/a=Sin(B)/b

3. The attempt at a solution

b^2=-6

You can plug in 1/2 in (cos(B)) right away.

Other attemps, dont ask what I did but I ended up finding A=pi/3 and that makes no sense.
