Trigonometry word problems (part 1)  Summary and Q&A
TL;DR
Use trigonometry to solve navigation problems by finding the distance between two points after being off course.
Questions & Answers
Q: What is the problem presented in the video?
The problem involves a ship that needs to navigate from point A to point B but ends up off course and needs to determine the remaining distance to its destination.
Q: How is trigonometry used to solve the navigation problem?
Trigonometry is used to calculate the lengths of the sides of a triangle formed by the ship's position, the desired destination, and the offcourse position. The known distances and angles are used to find the lengths of the remaining sides.
Q: What is the significance of the given angle of 15 degrees?
The angle of 15 degrees represents the deviation from the desired course. It helps determine the offcourse distance traveled by the ship and is crucial in calculating the remaining distance to the destination.
Q: What does the Pythagorean theorem help solve in this problem?
The Pythagorean theorem is used to find the length of the remaining distance by squaring the known distances and adding them together. This allows for the calculation of the remaining distance once the trigonometric equations have been simplified.
Summary & Key Takeaways

A ship needs to travel from point A to point B, but ends up off course after 5 kilometers, traveling in the wrong direction by 15 degrees.

By using trigonometry and breaking down the known distances and angles, the length of the remaining distance can be calculated.

The Pythagorean theorem is used to find the length of the remaining distance by squaring and simplifying the trigonometric equations.
