Show the answer
Correct answer: a) 34º 14.8’
Why it is correct
34º 04.0′ − 3.9′ dip − 1.4′ refraction + 16.1′ semi-diameter = 34º 14.8′.
Why the others are not
- b) It does not match the working.
- c) It does not match the working.
- d) It does not match the working.
How to work it out in the exam
- Index correction, dip (1.76 × √height), refraction and semi-diameter.
