Given the triangle ABC, a equals 45 degrees, B equals 75 degrees, B equals 8, find the edge a () a: 8 B: 4 C: 4 Given the triangle ABC, a equals 45 degrees, B equals 75 degrees, B equals 8, find the edge a () A：8 B：4 C：4√3－3 D：8√3－8

a/sinA=b/sinB
A / (radical 2 / 2) = 8 / [(radical 6 + radical 2) / 4]
A = 8 radical 3-8
D
Sine theorem is enough
