The Law of Sines and the Law of Cosines are also used to solve real-world problems that can be represented by an oblique triangle. Example 1: An eight metre telephone pole has a very bad lean and creates an angle greater than 90. with the ground. A guide wire, 14 m long, is attached to the pole for support so the pole. will not fall down.
