krissywatts 3 years ago i need help solving the following? to get the bearing of AB

1. krissywatts

2. kevin.chaithanya

Subtract 75degrees from 90degrees and that is the bearing of AB

3. kevin.chaithanya

|dw:1349501563244:dw|

4. krissywatts

okay and can you help me with one more?

5. kevin.chaithanya

That is the bearing of AB with north direction...is that what you want?

6. krissywatts

for this one i neeed azimuth and bearing?

7. krissywatts

i believe so

8. kevin.chaithanya

Give your next problem and I'll clarify it

10. krissywatts

it ask me what is the azimuth of cd and what is the bearing of cd

11. kevin.chaithanya

They must have given you a reference line or a starting line to find bearing and azimuth...

12. kevin.chaithanya

Yes, I got it...they gave you north as reference line because both of your diagrams of N mentioned...So,the answer to the first problem is 15 degrees(as said). In the second problem, the bearing and reference are the same..140degrees 39seconds

13. krissywatts

how did you get that? cause i'm trying to learn it and i don't know what i'm doing

15. kevin.chaithanya

Azimuth is the angle measured clock-wise from the reference line..

16. krissywatts

oh okay

18. krissywatts

i have like front and back pages to do on this

19. krissywatts

so i might come back later today

20. kevin.chaithanya

That is bearing....bearing is measured from east side and west side from the reference line...So, bearing can be a maximum of 180 degrees but azimuth can be a maximum of 360 degrees

21. krissywatts

okay

22. krissywatts

so would i get 129.35?

23. krissywatts

as the bearing?

24. kevin.chaithanya

In the second problem, both bearing and azimuth are the same....90+50.39 = 140.39
