For a line AB (a) *the azimuth of AB and back azimuth of AB differ by 180° (b) the azimuth of AB and back azimuth of BA differ by 180° (c) both (a) and (b) are correct. (d) none is correct 13. What is the percentage grade for a slope ratio of 1:13 (rise : run)? (a) 0.077 (b) 1.000 (c) *7.690 (d) 13.000 14. Using a right triangle, at the intersection point the slope distance or the hypotenuse is 240 feet long at a slope angle of 33 degrees 00' 00". What is the actual height distance? (a) 130.71 (b) 155.86 (c) 201.28 (d) 369.58 15. What are the length ratios for a right triangle? (a) 3:3:3 (b) 3:3:5 (c) 3:4:5 (d) 3:6:9Explanation / Answer
7) random errors are small errors that occur more frequently than the large errors. Correct option is c
8) setting out is the process of transferring a building design onto the land itself. Correct option is b
9)ranging is method os establishing intermediate points. Correct option is b
10)correct option is b. This is by definition pf cadastral surveying which involves establishment of property boundary
