Solve the triangle △ABC.
A = ?
C = 32°
B = 81°
a = ?
b = 13
c = ?
32° + 81° + A = 180°
113° + A = 180
A = 67° ✓
13 / sin (81) = c / sin (32)
13 sin (32) / sin (81) = c
6.888950435 / .9876883406 = c
6.9748 = c ✓
a / sin (67) = 13 / sin (81)
a = 13 sin (67) / sin (81)
a = 12.1157 ✓
A = 67°
C = 32°
B = 81°
a = 12.1157
b = 13
c = 6.9748 ✓
