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 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
