Math Problem Statement
Work out the bearing of point B from point A for Anson. The points form an equilateral triangle ABC, with point C due East of point B. You must show your working.
Solution
The problem describes a triangle where all angles are the same, meaning it's an equilateral triangle.
Key observations:
- Triangle is equilateral, so all angles are .
- Point is due east of point , meaning the line is horizontal.
- You are asked to find the bearing of point from point . Bearings are measured clockwise from the north.
Steps to solve:
- Since is equilateral, the angle at each vertex is . Specifically, the angle .
- We also know that the line from to is horizontal (due east). This means the angle from north at point to the line is the same as the interior angle of the equilateral triangle.
- To calculate the bearing of from , note that the bearing is measured clockwise from north. Since the angle at is and north points directly upward (vertically), the bearing is:
Thus, the bearing of point from point is 300°.
