WebThe boat turned 20 degrees, so the obtuse angle of the non-right triangle is the supplemental angle, 180° − 20° = 160°. With this, we can utilize the Law of Cosines to find the missing side of the obtuse triangle—the distance of the boat to the port. x2 = 82 + 102 − 2(8)(10)cos(160°) x2 = 314.35 x = √314.35 x ≈ 17.7miles.

The following are the formulas for cosine law for any triangles with sides a, b, c and angles A, B, C, respectively. a 2 = b 2 + c 2 − 2 b c cos A b 2 = a 2 + c 2 − 2 a c cos B c 2 = a 2 + b 2 − … In reference to the right triangle shown and from the functions of a right triangle: a/c …
In trigonometry, the law of cosines (also known as the cosine formula, cosine rule, or al-Kashi's theorem ) relates the lengths of the sides of a triangle to the cosine of one of its angles. Using notation as in Fig. 1, the law of cosines states where γ denotes the angle contained between sides of lengths a and b and opposite the side of length c. For the same figure, the other two relations are …
