In most practical cases, it is not necessary to compute a cosine value by hand, and a table ... To solve a triangle when we know two sides and the included angle, we will need a generalization of the Pythagorean theorem known as the Law of Cosines. In a …Practice set 1: Solving triangles using the law of sines This law is useful for finding a missing angle when given an angle and two sides, or for finding a missing side when given two angles and one side. Example 1: Finding a missing side Let's find AC AC in the following triangle: Law of Cosines: \(9^2=4^2+z^2-2 \cdot 4 \cdot z \cos 28^{\circ}\) or use the Law of Sines first to find the (acute) angle opposite the side of length 4, then find the angle opposite the side of length \(z\) by subtracting the sum of the known angles from \(180^{\circ}\), then using the Law of Sines again. The 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.Section 8.3: Proving Triangle Similarity by SSS and SAS.
