Question

The interior angles X, Y, and Z of a triangular traverse were measured with the same precision. The results were as follows:

X has interior angle of 41degrees with 3 number of measurement,Y has interior angle of 65degrees with 4 number of measurements nd Z has interior angle of 75 degrees with 2 number of measurements.

Answer 1

Answer

Given data are as

Angle value no. Of measurement

X 41^° 3

Y 65^° 4

Z 75^° 2

So total angle become as

X+Y+Z=181^°

In actual internal angle in triangle

X+Y+Z=180^°

So error is found

Error=181^°-180^°=1^°
