Follow the video on Homework Procedure.

Remember to always draw a sketch before you solve the problem.

1. Convert bearings to azimuths
a. N 300 09’ 56” E
b. N 140 12’ 20” W
c. S 800 56’ 09” E
d. S 080 15’ 50” W

2. Convert azimuths to bearings
a. 600 59’ 06”
b. 980 12’ 22”
c. 2050 40’ 51”
d. 3510 12’ 15”

3. Assume these bearings are for line A-B. Compute the azimuths for line B-A.
a. N 300 09’ 56” E
b. N 140 12’ 20” W
c. S 800 56’ 09” E
d. S 080 15’ 50” W

4. Bearing A-B is S 080 15’ 50” W. Bearing B-C is S 800 56’ 09” E. What is the clockwise
angle A-B-C?

5. Bearing A-B is N 080 18’ 50” W. Bearing B-C is S 800 56’ 09” E. What is clockwise
angle C-B-A?

6. Given a 4 sided polygon A-B-C-D-A with the following information:

Azimuth of A-B = 2030 40’ 12”
Angle A-B-C = 940 28’ 26” clockwise
Angle B-C-D = 1290 31’ 45” clockwise
Angle C-D-A = 540 33’ 33” clockwise
Angle D-A-B = 810 26’ 16” clockwise

a) Find the Azimuth of side B-C
b) Find the Azimuth of side C-D
c) Find the Azimuth of side D-A
d) Just given this information, do you think there is any error in the sum of the 4

angles? Why?

7. Given the Azimuth J-K is 400 44’ 00” and Angle K-J-P is 680 48’ 38” clockwise. What is
the Azimuth J-P?

8. Given the Azimuth F-G is 1470 21’ 36” and Angle F-G-H is 2550 06’ 18” clockwise.
What is the Azimuth G-H?

9. Given that Line A-B has the following Bearings:
N 670 22’ 30” W based on True North
N 560 10’ 12” W based on 2020 Magnetic North
N 580 41’ 28” W based on 1980 Magnetic North

What is:
a. 2020 Magnetic Declination
b. 1980 Magnetic Declination

10. Given that:

1950 Magnetic Declination is 140 12’ W
2020 Magnetic Declination is 130 40’ W
For Line C-B the 1950 Magnetic Bearing is S 03052’W

Find:
a. The True Bearing of Line C-B
b. The 2020 Magnetic Bearing of Line C-B
