3) Find AB 15° 34
Solution
It\'s easy to find angle B by using \'angles of a triangle add upto 180°\'. Therefore, A = 180° 24° 15° = 141°
We can now find side c = AB by using The Law of Sines:
a/sin A = c/sin C Then, we have 34/sin(141°) = AB/sin(15°) so that AB = (34 × sin(15°))/sin(141°) or, AB = 34* 0.2588/0.6293 or AB = 13.98 on rounding off to 2 decimal places
