Enter three values from a, A, b or B, and we can calculate the others (leave the values blank for the values you do not have):
a=, Angle(A)=°
b=, Angle(B)=°
c=, Angle(C)=°
\(\frac{a}{sin(A)}=\frac{b}{sin(B)}=\frac{c}{sin(C)}\)
\(A+B+C=180\)
\(B = \sin^{-1}{(\frac{b}{a}sin{A}})\)
\(B = 43.16°\)
\(C = 180-20.00-43.16=116.84\)
\(c = b\sin{C}/\sin{B}\)
