Step-by-step explanation:
The answers equivilant to 3 are 1,5,7
Pick the angle is closer to the middle (interior). 5
Given that the distance between two lines in the measurement instrument is 0.01m, the maximum error should be 0.01m/2 = 0.005 m.
If you do a good work, the real measure is 1.20m +/- 0.005m, this is between 1.195 and 1.205.
