Question

6. True of False (circle on) Cartesian coordinates are spherical relationships

7. ____________________________angles are measured clockwise 0 degrees to 360 degrees.

8. True of False (circle one) Typical bearing could be N 95*15’12” W.

This is a “trick” question, think about it.

9. Heron’s Formula is Area = Square root of s(s-a)(s-b)(s-c) . In this equation the “s” represents the ________________________________.

10. Convert 385*18’52” to decimal degrees._________________________.

Answer 1

6)True :the cartesian coordinates are spherical relationships with the coordinates representing a part component paralell to an axis.

7)Azimuths are angles that are measured clockwise from 0degrees to 360degrees.

8)False a vbearing cannot be N95^*15'12'' because the range os only between 0 and 90 degrees and after which the notation changes.

9)in gerons formula, the s b value represents the half of the sum of sides i.e (a+b+c)/2

10)385^*18'52'' can be converted as follows:

52''=52/3600 degrees=0.0144444 degrees

18'=18/60 degrees=0.186 degrees

therefore total value=385+0.186+0.01444 degrees

=385.330444 degrees.
