**Title: Understanding Angles in Traverse Surveying**
**Introduction:**
In surveying, open traverses are often used to measure and map out areas with a series of interconnected lines. An open traverse is illustrated in the diagram below with the points labeled G, H, I, and J. The angle between each segment is crucial for calculations in surveying.
**Diagram Explanation:**
- The diagram depicts an open traverse comprising four points: G, H, I, and J.
- There is an angle measured at point H labeled as 153°30'05".
- Another angle is shown at point J labeled as 34°20'57".
**Problem Statement:**
Based on the information provided, students are required to determine the following:
a. **The deflection angle at point H.**
b. **The internal angle at point I.**
c. **Determine the azimuth of lines HI and IJ given that the azimuth of line GH is 125°00'00".**
**Objectives:**
1. Develop an understanding of deflection and internal angles in a traverse.
2. Practice calculating azimuths between connected lines.
**Instructions:**
Use the diagram and the given azimuths to complete the following exercises. Remember to apply your understanding of bearings and angle conversions where necessary.
For students to successfully calculate and solve this, familiarity with basic trigonometry, angle addition, and azimuth interpretation in the context of surveying is essential.
