Geomatics Engineering Question on Distance and angle measurement
Independent angles AOB, BOC and AOC were observed as shown in figure. The standard error of all observations is same. The adjusted values of these angles using the least squares adjustment are
A
AOB = 30°00′15′′, BOC = 30°00′00′′, AOC = 60°00′15′′
B
AOB 30°00'10", BOC = 30°00'05", AOC = 60°00'15"
C
AOB = 30°00'05", BOC = 30°00'10", AOC = 60°00'15"
D
AOB 30°00'10", BOC = 30°00'10", AOC = 60°00′20′′
Answer
AOB = 30°00′15′′, BOC = 30°00′00′′, AOC = 60°00′15′′
Explanation
Solution
The correct answer is (A) : AOB = 30°00′15′′, BOC = 30°00′00′′, AOC = 60°00′15′′
