  2. Given the following information, find m B1 : m A = 20°, a = 12, b = 31 b = 31 a = 12 62.1° 20° A B1 sin 20° sin B1° = 12 31 31 sin 20° sin B1° = 12 ≈ B1° sin-1 ( 0.8835520369) ≈ B1° 62.1°

  3. Given the following information, find m B2: b = 31 12 12 180° 20° A 62.1° 62.1° B2 B1 180° ─ 62.1° = 117.9°

  4. Given the following information, find m B2: b = 31 a = 12 117.9° 20° A B2 B1 180° ─ 62.1° = 117.9°
