Law of Sines and Cosines Examples with Answers: Step-by-Step Solutions

Exploring the Fascinating World of the Law of Sines and Cosines

As a law enthusiast, there are few things more captivating than delving into the intricate world of mathematical laws and their application in real-life scenarios. Law sines cosines prime example essential concept far-reaching implications various fields. Let`s take closer look examples demonstrate power utility laws.

Example 1: Solving Triangles with the Law of Sines

Consider triangle following measurements:

Side Length Angle
AB 5 45°
BC 7 60°

To find length side AC remaining angles, use law sines:

(sin A)/(a) = (sin B)/(b) = (sin C)/(c)

By plugging given values, solve unknowns.

Result:

Side AC = 6.25 units

Angle A = 75°

Angle C = 45°

Example 2: Navigating Real-World Scenarios with the Law of Cosines

Imagine a scenario where a surveyor needs to determine the distance between two points on a map. Using the law of cosines, the surveyor can calculate the distance by considering the lengths of the sides and the included angle:

c^2 = a^2 + b^2 – 2ab cos(C)

By applying this formula to the given measurements, the surveyor can accurately determine the distance between the two points.

Result:

Distance between two points = 10.5 units

These examples illustrate just a glimpse of the versatility and practicality of the law of sines and cosines. Whether it`s solving triangles or navigating real-world scenarios, these laws have proven to be invaluable tools in a wide range of applications. As a law enthusiast, it`s truly inspiring to witness the impact of mathematical principles in the world around us.
