Law of sines: A = 30°, B = 60°, a = 10
Find the third angle and the two remaining sides with the law of sines.
Solution
- Given A = 30°, B = 60°, side a = 10
- Third angle C = 180° − A − B = 90°
- Law of sines a / sin A = 10 / 0.5 = 20
- Side b b = (a/sin A)·sin B = 17.3205
- Side c c = (a/sin A)·sin C = 20
