Question
Interior angles measured at the locations of a closed traverse ABCDA are given in table below.
The total error in the measured angles (in degrees) is ______________ (rounded off to three decimal places).
| Location | Interior angle |
|---|---|
| A | |
| B | |
| C | |
| D |
Correct answer
0.18 to 0.184
Solution
1.Theoretical sum of interior angles for a closed traverse with sides:
Sum 2.Calculate the measured sum:
Degrees: Minutes:
Seconds:
3.Simplify the sum:
Total minutes
Total measured sum
4.Calculate the error:
Error 5.Convert error to degrees:
Error (degrees) 6.Rounding to three decimal places, we get 0.182.
