How Do You Calculate Total Displacement Using the Component Method?

In summary, the component method for vectors is a mathematical technique used to break down a vector into its x and y components, which are its horizontal and vertical parts. It is used in physics to analyze the motion of an object in two or three dimensions, by determining the direction and magnitude of the object's motion. The components of a vector can be found by using trigonometric functions based on the vector's angle and magnitude. The advantages of using the component method include simplifying calculations, providing a comprehensive analysis of motion, and utilizing trigonometric functions for more accurate calculations.

The Attempt at a Solution



I thought I just had to find the third unknown side, and use the pythagorean theorem, but I was getting the wrong answer. My book says 11 km.

Any help is appreciated.
