Math Problem Statement

using pythagorean theorem, sine law and cosine law

Determine the bearing of 4-1 and distance of 3-4.

Solution

To determine the missing values:

Task Summary:

  1. Find the bearing of line 4-1.
  2. Determine the distance of line 3-4.

Let's proceed with each task step-by-step.


1. Find the Distance of Line 3-4

From the table, the bearings and distances of lines 1-2, 2-3, and 4-1 are given. To calculate the distance of 3-4, we'll use the Pythagorean theorem, sine law, or cosine law as needed.

However, without coordinates, solving it directly may need assuming coordinate values or using a trigonometric layout based on bearings and distances.
