if B=30 degrees, C=45 degrees, then A=180-(B+C) degrees,
A=180-(30+45)=105 degrees
Use the law of sines

if a=√3+1,B=30 degrees, C=45 degrees then c=?
**
Let A, B, & C be the 3 angles of a triangle, and a, b, and c the corresponding sides opposite these angles:
A+B+C=180º
A+30+45=180
A=180-75=105º
Using Law of Sines
sin A/a=sin C/c
c=(sin C/sin A)*a
c=(sin 45/sin 105)*√3+1
c=2
