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. WebIn trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles. According to the law, where a, b, and c are the lengths of the sides of a triangle, and α, β, and γ are the opposite angles (see figure 2), while R is the radius of the triangle ... WebTo derive the formula, erect an altitude through B and label it h B as shown below. Expressing h B in terms of the side and the sine of the angle will lead to the formula of the sine law. sin A = h B c. h B = c sin A. sin C = h B a. h B = a sin C. Equate the two h B 's above: h B = h B. c sin A = a sin C. porsche inter auto maribor
